Summary:
This diffs add a layer of indirection between fbinit and tokio, thus allowing
us to use fbinit with tokio 0.2 or tokio 1.x.
The way this works is that you specify the Tokio you want by adding it as an
extra dependency alongside `fbinit` in your `TARGETS` (before this, you had to
always include `tokio-02`).
If you use `fbinit-tokio`, then `#[fbinit::main]` and `#[fbinit::test]` get you
a Tokio 1.x runtime, whereas if you use `fbinit-tokio-02`, you get a Tokio 0.2
runtime.
This diff is big, because it needs to change all the TARGETS that reference
this in the same diff that introduces the mechanism. I also didn't produce it
by hand.
Instead, I scripted the transformation using this script: P242773846
I then ran it using:
```
{ hg grep -l "fbinit::test"; hg grep -l "fbinit::main" } | \
sort | \
uniq | \
xargs ~/codemod/codemod.py \
&& yes | arc lint \
&& common/rust/cargo_from_buck/bin/autocargo
```
Finally, I grabbed the files returned by `hg grep`, then fed them to:
```
arc lint-rust --paths-from ~/files2 --apply-patches --take RUSTFIXDEPS
```
(I had to modify the file list a bit: notably I removed stuff from scripts/ because
some of that causes Buck to crash when running lint-rust, and I also had to add
fbcode/ as a prefix everywhere).
