Summary: I'm about to introduce one more usecase of it so let's rename it first.

Summary:
Context: https://fb.workplace.com/groups/rust.language/permalink/3338940432821215/
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.

Summary:
In targets that depend on *both* 0.1 and 0.3 futures, this codemod renames the 0.1 dependency to be exposed as futures_old::. This is in preparation for flipping the 0.3 dependencies from futures_preview:: to plain futures::.

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.
