Summary:
This diff prepares the Mononoke codebase for composition-based extendability of
`ScubaSampleBuilder`. Specifically, in the near future I will add:
- new methods for verbose scuba logging
- new data field (`ObservabilityContext`) to check if verbose logging should
be enabled or disabled
The higher-level goal here is to be able to enable/disable verbose Scuba
logging (either overall or for certain slices of logs, like for a certain
session id) in real time, without restarting Mononoke. To do so, I plan to
expose the aforementioned verbose logging methods, which will run a check
against the stored `ObservabilityContext` and make a decision of whether the
logging is enabled or not. `ObservabilityContext` will of course hide
implementation details from the renamed `ScubaSampleBuilderExt`, and just provide a yes/no
answer based on the current config and sample fields.
At the moment this should be a completely harmless change.

To support the ability for Mercurial to talk to Mononoke directly while going
through an HTTP proxy, we need to be able to accept HTTP prefixed requests.
This adds the support for Mononoke side. Mercurial client will be added in

Summary: As part of the effort to deprecate futures 0.1 in favor of 0.3 I want to create a new futures_ext crate that will contain some of the extensions that are applicable from the futures_01_ext. But first I need to reclame this crate name by renaming the old futures_ext crate. This will also make it easier to track which parts of codebase still use the old futures.

Summary:
This will give us the host that hgcli is running on, which is, like, convenient
to know what hg host proxied a request. For comparison, currently, we have to
go through ssh prod logs using the client IP and port, and hope there aren't
too many matches, which is really not a reasonable way to debug things.

Summary:
This takes johansglock's D23757705 one step further, and gets rid of the
`Wait<...>` wrapper we use to synchronously write to stderr in our logging on
the Mononoke Server side.
This should be fine because We send very little logs to the client, so just
buffering them seems like it won't really hurt, and even if we were writing a
log, it certainly would hurt less than blocking our runtime threads into an
interruptible wait.
A problem is that we actually use this in hgcli, where we want to read from our
stdin and write to our stdout / stderr. Rather than port all this stuff, this
diff updates hgcli to just use Tokio's abstractions for stdink, stdout, and
stderr. I ported the various buffer sizes we use to use there in here (I think
we should buffer less from the server though — 50000 buffers is a lot).
I did however update this to write to `std::io::stderr()` instead of an async
stream for this. I think it's fine considering:
- Internally, Tokio also uses `std:io::stderr()` which has a lock on writing.
- We hardly write anything anyway

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.

Summary:
This largely moves connection accepting from old style bytes, futures and tokio
to updated versions, while keeping some parts at old bytes/futures in order to
remain compatible with the rest of the Mononoke codebase.
Division lies on `Stdio` which maintains old channels, stream and futures,
while the socket handling, connection acception and wire encoding is updated.
With the updated futures, we now wait for the forwarding stream to have
succeeded before considering a connection fully handled.
Other notable changes:
- futures_ext now a mini codec Decoder instead of relying on NetstringDecoder,
which has been updated to use bytes 0.5
- hgcli has been modified to use updated NetstringDecoder
- netstring now requires the updated bytes 0.5 crate
- the part in connection_acceptor was handling repo/security logic is now part of repo_handler (as it should have been), connection_acceptor now only handles networking and framing
- tests now verify that the shutdown handler is triggered

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`.

`flush()` takes a timeout, which is in milliseconds. However, that's not super
obvious, so that means whoever is using this has to re-discover it. Let's make

This codemod replaces *all* dependencies on `//common/rust/renamed:futures-preview` with `fbsource//third-party/rust:futures-preview` and their uses in Rust code from `futures_preview::` to `futures::`.
This does not introduce any collisions with `futures::` meaning 0.1 futures because D20168958 previously renamed all of those to `futures_old::` in crates that depend on *both* 0.1 and 0.3 futures.
