chore: Prepare 0.8 release (#1044)

chore: Prepare `0.7.2` release (#998)

bump tonic to 0.7.1

chore: Prepare aux crates for release (#955)

chore: Prepare 0.6.2 (#860)

- Contains the revert to [rust 2018](#847).
- Bumps both tonic and tonic-build.
- tonic-build goes from 0.6.0 to 0.6.2 since there was no 0.6.1. I
  believe we want tonic and tonic-build versions to follow each other.

chore: Prepare 0.6.1 (#814)

chore: Prepare `0.6.0` release (#811)

chore: Prepare tonic v0.5.2 (#738)

So as highlighted by
#730 (comment) it
turns out the new `Interceptor` trait required changes to tonic-build as
well, which I forgot to publish yesterday. Didn't see it because it wasn't
clear from the commit message.

So this bumps tonic _and_ tonic-build to 0.5.2 so we can release both.
There are no code changes.

chore: Prepare tonic v0.5.1 and tonic-health 0.4.1 (#737)

Fix tonic-types and health versions
