* Fix CI by explicitly setting hostname of docker in docker service
* Fix Docker build by bumping the Rust version to 1.69
* Fix cargo check in CI by bumping the Rust version to 1.69
This moves compiler caching for incremental builds away from GitLab
caching the whole target/ folder to caching each code unit in S3.
This aleviates the need to zip and unzip and just caches on the fly.
This feature is optional and gated behind the SCCACHE_BIN_URL env
gcc-8-aarch64-linux-gnu is not available in debian 11 (which the rust image uses), so update to gcc-10

- Build release builds for branches "master" and "next"
- Push docker images under different tags, depending on why the pipeline started
- branch master: push to `latest`
- branch next: push to `next`
- tag: push to `$TAG_NAME`

Using `$CI_COMMIT_REF_NAME` means we get `master` for every image build,
which is not very useful/informative. Using `$CI_COMMIT_SHORT_SHA`,
on the other hand, makes it possible to see exactly from which commit an
image was built.
The average german man has a life expectancy of 78.7 years, or 689884.2 hours.
Assuming that Timo is 20 years old, he has rougly 514564.2 hours left on planet earth.
Also assuming that cross release builds took him 25 minutes before,
but 2-2.5x of that with the current release compilation config he wasted roughly an hour waiting for it to complete.
If he continued to work on Conduit for 20 more years (or 175320 hours),
and makes a release compilation about once per day, this means 7305 hours or 304 days wasted waiting for the rust compiler.
By cutting that back down to the original settings, he get's 182 days of his life back.
That's about 0.63% of his remaining life.
182 joyful days he can spend with family and loved ones.
Testing needs compilation and is slow. Format checking is quick.
As format checking fails more often than tests,
switching them should result in faster failure and feedback
