Summary:
Update from 1.44.0. Updates have been blocked because of a bad interaction
between platform007+mode/opt-clang-thinlto+gold. Now that the default linker is
lld, perhaps this is no longer an issue.
Various tweaks due to updates:
- `atomic_min_max`, `const_transmute`, `inner_deref`, `ptr_offset_from` and `str_strip` are now stable
- `asm` renamed to `llvm_asm`
- `intra_doc_link_resolution_failure` lint renamed to `broken_intra_doc_link` (ndmitchell I didn't fix Gazebo because you'd explicitly suppressed the warning - I'll let you work out what to do with that)
(This is caused by incompatibility between the llvm used by rustc in
platform007 and llvm-fb. In platform009, rustc uses llvm-fb directly so there's
no scope for incompatibility.)

Summary:
This diff introduces Mysql client for Rust to Mononoke as a one more backend in the same row with raw xdb connections and myrouter. So now Mononoke can use new Mysql client connections instead of Myrouter.
To run Mononoke with the new backend, pass `--use-mysql-client` options (conflicts with `--myrouter-port`).
I also added a new target for integration tests, which runs mysql tests using mysql client.
Now to run mysql tests using raw xdb connections, you can use `mononoke/tests/integration:integration-mysql-raw-xdb` and using mysql client `mononoke/tests/integration:integration-mysql`

Summary:
This diff makes blobstore healer to use MyAdmin to get replication lag for a DB shard and removes "laggable" interface for connections.
The old "laggable" API worked this way: we maintained potential connections to each possible region, then tried to query replica status on all of them. If there was no replica hosts in some of the regions, we just wanted to ignore it by handling a specific error type.
This is legacy and makes the logic more complicated. We want for the new code to use Myadmin instead.

Summary:
In preparation of moving away from SSH as an intermediate entry point for
Mononoke, let Mononoke work with newly introduced Metadata. This removes any
assumptions we now make about how certain data is presented to us, making the
current "ssh preamble" no longer central.
Metadata is primarily based around identities and provides some
backwards-compatible entry points to make sure we can satisfy downstream
consumers of commits like hooks and logs.
Simarly we now do our own reverse DNS resolving instead of relying on what's
been provided by the client. This is done in an async matter and we don't rely
on the result, so Mononoke can keep functioning in case DNS is offline.

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

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,

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.

Summary:
This introduces caching of filenodes to Memcache as in the old filenodes
implementation. The code is mostly was ported over from the existing filenodes
implementation, and converted to async / await. However, one key difference is
that the lookups happen once we hold the semaphore to talk to the underlying
MySQL shard.
The reason for this is:
- Reads to Memcache are really fast. They're often under 1ms. If you're going
to miss in Memcache and have to go to SQL, it won't make you much slower.
- Reads to Memcache are kinda expensive CPU-wise. Data in Memcache is
compressed, and we often see a lot of our CPU cycles spent talking to Memache
when we're under load.
- Memcache isn't an infinite resource. If we're reading the exact same
key a hundred times, that's going to hit the same Memcache box. A bit of
deduplication on our end is a nice thing to strive for. Besides, our own
thread pool we use to talk to Memcache is limited in size.
From a performance perspective, this doesn't make things any slower, but
reduces CPU usage when we'd otherwise have a lot of duplicate fetching.
Finally, note that this update also includes support for dirty-tracking in our
local cache. We use this to know if we should fill the remote cache (if we 100%
hit in local cache, we don't fill the remote cache).
