Summary: D22381744 updated the version of `futures` in third-party/rust to 0.3.5, but did not regenerate the autocargo-managed Cargo.toml files in the repo. Although this is a semver-compatible change (and therefore should not break anything), it means that affected projects would see changes to all of their Cargo.toml files the next time they ran `cargo autocargo`.

Summary:
At the moment we can't test logging to scribe easily - we don't have a way to
mock it. Scribe are supposed to help with that.
They will let us to configure all scribe logs to go to a directory on a
filesystem similar to the way we configure scuba. The Scribe itself will
be stored in CoreContext

Summary: This diff introduces `BlobRepoHg` extension trait for `BlobRepo` object. Which contains mercurial specific methods that were previously part of `BlobRepo`. This diff also stars moving some of the methods from BlobRepo to BlobRepoHg.

Summary:
Currently, Mononoke's configs are loaded at startup and only refreshed
during restart. There are some exceptions to this, including throttling limits.
Other Mononoke services (such as the LFS server) have their own implementations
of hot reloadable configs, however there isn't a universally agreed upon method.
Static configs makes it hard to roll out features gradually and safely. If a
bad config option is enabled, it can't be rectified until the entire tier is
restarted. However, Mononoke's code is structured with static configs in mind
and doesn't support hot reloading. Changing this would require a lot of work
(imagine trying to swap out blobstore configs during run time) and wouldn't
necessarily provide much benefit.
Instead, add a subset of hot reloadable configs called tunables. Tunables are
accessible from anywhere in the code and are cheap to read as they only require
reading an atomic value. This means that they can be used even in hot code
paths.
Currently tunables support reloading boolean values and i64s. In the future,
I'd like to expand tunables to include more functionality, such as a rollout
percentage.
The `--tunables-config` flag points to a configerator spec that exports a
Tunables thrift struct. This allows differents tiers and Mononoke services to
have their own tunables. If this isn't provided, `MononokeTunables::default()`
will be used.
This diff adds a proc_macro that will generate the relevant `get` and `update`
methods for the fields added to a struct which derives `Tunables`. This struct is
then stored in a `once_cell` and can be accessed using `tunables::tunables()`.
To add a new tunable, add a field to the `MononokeTunables` struct that is of
type `AtomicBool` or `AtomicI64`. Update the relevant tunables configerator
config to include your new field, with the exact same name.
Removing a tunable from `MononokeTunables` is fine, as is removing a tunable
from configerator.
If the `--tunables-config` path isn't passed, then a default tunables config
located at `scm/mononoke/tunables/default` will be loaded. There is also the
`--disable-tunables` flag that won't load anything from configerator, it
will instead use the `Tunable` struct's `default()` method to initialise it.
This is useful in integration tests.

Summary:
This is needed because the tonic crate (see the diff stack) relies on tokio ^0.2.13
We can't go to a newer version because a bug that affects mononoke was introduced on 0.2.14 (discussion started on T65261126). The issue was reported upstream https://github.com/tokio-rs/tokio/issues/2390
This diff simply changed the version number on `fbsource/third-party/rust/Cargo.toml` and ran `fbsource/third-party/rust/reindeer/vendor`.
Also ran `buck run //common/rust/cargo_from_buck:cargo_from_buck` to fix the tokio version on generated cargo files

Summary:
We had accumulated lots of unused dependendencies, and had several test_deps in deps instead. Clean this all up to reduce build times and speed up autocargo processing.
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.
