Summary:
Add a regex for repo prefix detection, and use it in prefixblob for removal of repo prefix from blob-embedded keys.
This is important to keep blobs copyable between repos, and to allow dedupe between same blob in two repos.
I looked at alternate approaches of passing down the prefix from PrefixBlob::new(), but that was fragile and didn't cover the use cases from things like blobstore_healer where no prefixblob is configured at all but packblob will be in the blobstore stack. Using a pattern is the only real option in such "all repo" cases.
The aim of binding the pattern and its tests closely to the prefix generation is to make it hard for someone to get them out of sync, and provide a clear local test failure if they do.

CountedBlobstore is a Blobstore that wraps another blobstore in order

CountedBlobstore exposes metrics that are supposed to track the number of hits
or misses when fetching blobs. However, these metrics don't make sense as the
CountedBlobstore has no view into cache activity. These metrics actually report
the number of requests and the number of missing blobs rather than hits and
misses.

Limits on concurrent calls are a bit hard to reason about, and it's not super
obvious what a good limit when all our underlying limits are expressed in QPS
(and when our data sets don't have peak concurrency - instead they have
completion time + # blob accesses).
Considering our past experience with ThrottledBlob has been quite positive
overall, I'd like to just use the same approach in ContextConcurrencyBlobstore.
To be safe, I've also updated this to be driven by tunables, which make it
easier to rollout and rollback.
Note that I removed `Debug` on `CoreContext` as part of this because it wasn't
used anywhere. We can bring back a meaningful implementation of `Debug` there
in the future if we want to. That triggered some warnings about unused fields,
which for now I just silenced.

Summary:
There was a bug in scrub blobstore that caused failures while traversing the
fsnodes.
If all blobstores returned None, then we need to return None and not fail as we
do now. So the situation we ran into was:
1) fsnodes is not derived, all blobstore return None
2) Previously it returned the error, which later checked in
https://fburl.com/diffusion/mhhhnkxv - this check makes sure there's no entry
with the same key on the queue. However by that time fsnodes might already be
derived and someone else might insert a new entry in the blobstore and in the
queue. This would return an error to the client.
The fix here is to not fail if all blobstores returned None

Summary:
We have a number of error enums that wrap an existing errors, but fail to
register the underlying error as a `#[source]`. This results in truncated
context chains when we print the error. This fixes that. It also removes a
bunch of manual `From` implementation that can be provided by thiserror's
`#[from]`.
This also required updating the `Display` implementation for those errors. I've
opted for not printing the underlying error, since the context chain will
include it. This does mean that if we print one of those errors without the
context chain (i.e. `{}` as opposed to `{:#}` or `{:?}`), then we'll lose out a
bit of context. That said, this should be OK, as we really shouldn't ever being
do this, because we'd be missing the rest of the chain anyways.

Summary:
RepoBlobstore is currently a type alias for the underlying blobstore type. This
is a bit unideal for a few reasons:
- It means we can't add convenience methods on it. Notably, getting access to
the underlying blobstore can be helpful in tests, but as-is we cannot do that
(see the test that I updated in the LFS server change in this diff for an
example).
- Since the various blobstores we use for wrapping are blobstores themselves,
it is possible when deconstructing the repo blobstore to accidentally forget
to remove one layer. By making the internal blobstore a `T`, we can let the
compiler prove that deconstructing the `RepoBlobstore` is done properly.
Most of the changes in this diff are slight refactorings to make this compile
(e.g. removing obsolete trait bounds, etc.), but there are a couple functional
changes:
- I've extracted the RedactedBlobstore configuration into its own Arc. This
enables us to pull it back out of a RedactedBlobstore without having to copy
the actual data that's in it.
- I've removed `as_inner()` and `into_inner()` from `RedactedBlobstore`. Those
methods didn't really make sense. They had 2 use cases:
- Deconstruct the `RedactedBlobstore` (to rebuild a new blobstore). This is
better handled by `as_parts()`.
- Get the underlying blobstore to make a request. This is better handled by
yielding the blobstore when checking for access, which also ensures you
cannot accidentally bypass redaction by using `as_inner()` (this which also
allowed me to remove a clone on blobstore in the process).

Summary:
Migrate the configuration of sql data managers from the old configuration using `sql_ext::SqlConstructors` to the new configuration using `sql_construct::SqlConstruct`.
In the old configuration, sharded filenodes were included in the configuration of remote databases, even when that made no sense:
```
[storage.db.remote]
db_address = "main_database"
sharded_filenodes = { shard_map = "sharded_database", shard_num = 100 }
[storage.blobstore.multiplexed]
queue_db = { remote = {
db_address = "queue_database",
sharded_filenodes = { shard_map = "valid_config_but_meaningless", shard_num = 100 }
}
```
This change separates out:
* **DatabaseConfig**, which describes a single local or remote connection to a database, used in configuration like the queue database.
* **MetadataDatabaseConfig**, which describes the multiple databases used for repo metadata.
**MetadataDatabaseConfig** is either:
* **Local**, which is a local sqlite database, the same as for **DatabaseConfig**; or
* **Remote**, which contains:
* `primary`, the database used for main metadata.
* `filenodes`, the database used for filenodes, which may be sharded or unsharded.
More fields can be added to **RemoteMetadataDatabaseConfig** when we want to add new databases.
New configuration looks like:
```
[storage.metadata.remote]
primary = { db_address = "main_database" }
filenodes = { sharded = { shard_map = "sharded_database", shard_num = 100 } }
[storage.blobstore.multiplexed]
queue_db = { remote = { db_address = "queue_database" } }
```
The `sql_construct` crate facilitates this by providing the following traits:
* **SqlConstruct** defines the basic rules for construction, and allows construction based on a local sqlite database.
* **SqlShardedConstruct** defines the basic rules for construction based on sharded databases.
* **FbSqlConstruct** and **FbShardedSqlConstruct** allow construction based on unsharded and sharded remote databases on Facebook infra.
* **SqlConstructFromDatabaseConfig** allows construction based on the database defined in **DatabaseConfig**.
* **SqlConstructFromMetadataDatabaseConfig** allows construction based on the appropriate database defined in **MetadataDatabaseConfig**.
* **SqlShardableConstructFromMetadataDatabaseConfig** allows construction based on the appropriate shardable databases defined in **MetadataDatabaseConfig**.
Sql database managers should implement:
* **SqlConstruct** in order to define how to construct an unsharded instance from a single set of `SqlConnections`.
* **SqlShardedConstruct**, if they are shardable, in order to define how to construct a sharded instance.
* If the database is part of the repository metadata database config, either of:
* **SqlConstructFromMetadataDatabaseConfig** if they are not shardable. By default they will use the primary metadata database, but this can be overridden by implementing `remote_database_config`.
* **SqlShardableConstructFromMetadataDatabaseConfig** if they are shardable. They must implement `remote_database_config` to specify where to get the sharded or unsharded configuration from.

because its SQL queries timing out. The rootcause of the problem
is that the same blob_key may show up on the queue many times repeatedly
and the query is trying to select all occurences.
But, the original intention of blobstore healer is to act on a single
put operation across all blobstores. To be able to identify which
puts in the healer queue are part of the same operation we need
some unique id that we'll use per such operation, let's call it OperationKey.
corresponding configerator change to create db column: D20557659
NOTE: This diff has to be landed and rolled out first, before D20557700 is rolled out. I'm assuming that after some time since rolling out this diff all the rows in the production db will have proper `operation_key` value set.

Summary:
This is a small refactoring that does two things:
1) Move StoreLoadable into the Blobstore crate. This might be a bit
controversial since StoreLoadable doesn't have anything to do with blobstore.
But I put it there for a few reasons:
* In the next diffs I want to use StoreLoadable in mononoke_types. However I
can't create dependency from `mononoke_types` crate to `manifest` crate because
`manifest` depends on `mononoke_types`
* `manifest` crate doesn't look like a good place for this struct either
* I didn't find a better place for it - don't want to put it in crates like
`common`, and it creating a separate crate just for this trait looks like an
overkill.
2) Changes error type to LoadableError to match Loadable trait. This add one
FIXME for git tree which doesn't differentiate between these errors.

Summary:
Right now, ContextConcurrencyBlobstore is instantiated in make_blobstore, which
makes it a lot more effective (3 times more effective, in fact) than we want it
to be, since a ticket is acquired by 3 blobstores in the chain in order to
complete a put:
- The multiplex
- The two underlying blobstores
This also has the potential to deadlock if all tickets are held by the
multiplex, which results in an eventual timeout after 600s of waiting in the
multiplex (this looks like it might be happening at least once or twice per
hour right now on the experimental tier).
In any case, the intention had always been to have one of those per repo, not
one per sub-blobstore, so let's do that. The more natural place to put this
seems to be the RepoBlobstore instantiation.
Since I anticipate I might not be the only one who gets tripped up by this at
some point, I also added a comment about this. I also updated the blobsync
tests to stop re-implementing `RepoBlobstoreArgs::new()` so that adding new
blobstores in RepoBlobstoreArgs will have minimal friction.

Summary:
The Bytes 0.5 update left us in a somewhat undesirable position where every
access to our blobstore incurs an extra copy whenever we fetch data out of our
cache (by turning it from Bytes 0.5 into Bytes 0.4) — we also have quite a few
place where we convert in one direction then immediately into the other.
Internally, we can start using Bytes 0.5 now. For example, this is useful when
pulling data out of our blobstore and deserializing as Thrift (or conversely,
when serializing and putting it into our blobstore).
However, when we interface with Tokio (i.e. decoders & encoders), we still have
to use Bytes 0.4. So, when needed, we convert our Bytes 0.5 to 0.4 there.
The tradeoff idea is that we deal with more bytes internally than we end up
sending to clients, so doing the Bytes conversion closer to the point of
sending data to clients means less copies.
We can also start removing those once we migrate to Tokio 0.2 (and newer
versions of Hyper for HTTP services).
Changes that were required:
- You can't extend new bytes (because that implicitly copies). You need to use
BytesMut instead, which I did where that was necessary (I also added calls in
the Filestore to do that efficiently).
- You can't create bytes from a `&'a [u8]`, unless `'a` is `'static`. You need
to use `copy_from_slice` instead.
- `slice_to` and `slice_from` have been replaced by a `slice()` function that
takes ranges.

Summary:
Nearly all of the Mononoke SQL stores are instantiated once per repo but they don't store the `RepositoryId` anywhere so every method takes it as argument. And because providing the repo_id on every call is not ergonomical we tend to add methods to blob_repo that just call the right method with the right repo_id in on of the underlying stores (see `get_bonsai_from_globalrev` on blobrepo for example).
Because my reviewers [pushed back](https://our.intern.facebook.com/intern/diff/D19972871/?transaction_id=196961774880671&dest_fbid=1282141621983439) when I've tried to do the same for bonsai_git_mapping I've decided to make it right by adding the repo_id to the BonsaiGitMapping.

Summary:
This updates our multiplexed blobstore configuration to carry its own DB
config. The upshot of this change is that we can move the blobstore sync queue
(a fairly unruly table) to its own DB.
Another nice side effect of this is that it cleans up a bunch of other code, by
finally decoupling the blobstore config from the DB config. For examples,
places that need to instantiate a blobstore can now to do even without a DB
config (such as wireproto logging).
Obviously, this cannot land until we update the configs to include this. I'll
do so in Configerator prior to landing the diff.

Summary:
This allows code that is being exercised under async_unit to call into code
that expects a Tokio 0.2 environment (e.g. 0.2 timers).
Unfortunately, this requires turning off LSAN for the async_unit tests, since
it looks like LSAN and Tokio 0.2 don't work very well together, resulting in
LSAN reporting leaked memory for some TLS structures that were initialized by
tokio-preview (regardless of whether the Runtime is being dropped):
https://fb.workplace.com/groups/rust.language/permalink/3249964938385432/
Considering async_unit is effectively only used in Mononoke, and Mononoke
already turns off LSAN in tests for precisely this reason ... it's probably
reasonable to do the same here.
The main body of changes here is also about updating the majority of our
changes to stop calling wait(), and use this new async unit everywhere. This is
effectively a pretty big batch conversion of all of our tests to use async fns
instead of the former approaches. I've also updated a substantial number of
utility functions to be async fns.
A few notable changes here:
- Some pushrebase tests were pretty flaky — the race they look for isn't
deterministic. I added some actual waiting (using pushrebase hooks) to make
it more deterministic. This is kinda copy pasted from the globalrev hook
(where I had introduced this first), but this will do for now.
- The multiplexblob tests don't work at all with new futures, because they call
`poll()` all over the place. I've updated them to new futures, which required
a bit of reworking.
- I took out a couple tests in async unit that were broken anyway.
