Summary:
I observed that for whatever reason our setting of `use_try_shorthand = true` in rustfmt.toml was causing entire functions to not get processed by rustfmt. Even files that contain neither `try` nor `?`. Remove it and reformat fbsource.
Documentation of that config:
- https://github.com/rust-lang/rustfmt/blob/master/Configurations.md#use_try_shorthand
We don't particularly care about the value anymore because nobody writes `r#try!(...)` in 2018 edition code.
Minimized:
```
fn f() {
g(
)
// ...
.h
}
```
This function gets formatted only if use_try_shorthand is not set.
The bug is fixed in the rustfmt 2.0 release candidate.

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.

Net removal is of around 500 unneeded dependency lines, which represented false dependencies; by removing them, we should get more parallelism in dev builds, and less overbuilding in CI.

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:
We are planning to expand our usage of warm bookmark cache beyond scs server.
In particular we'd like to use it in mononoke server. But before we do that let's
make warm bookmark cache a bit more reliable and predictable.
In particular, let's make sure that slow update of a single bookmark doesn't
block progress of all other bookmarks - for example, we don't want to block
updating master if we have problems with a single release bookmark. See more
discussion about it in D20161458. [1]
In order to do that we now update every bookmark separately - bookmarks updater
job spawns updater for a single bookmark and makes sure there's no more than a
single updater for a given bookmark.
A few caveats:
1) After this diff we no longer preserve an order of updates of a bookmark i.e.
even if bookmark A was updated first then bookmark B, warm bookmark cache might
see updated in different order. We expect it to not matter much with the only
caveat being stable and master boomarks - it'd be weird to have stable being
descendant of master. This glitch should only happen for a very brief time
period of time, so hopefully it shouldn't matter in practice.
2) Current implementation doesn't stop single bookmark updaters if the main
updater was cancelled. TBH, I don't think it's necessary.
In the next diff I'll add ods counters to track the delay between warm bookmark cache and actual
values of bookmarks
[1] Previously we wanted to update bookmarks in bookmark update log order, but
we decided it's not a great idea. See D20161458 for more details.

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.
