Bazel CI

[fmorency]

• CI uses Bazel for lint/build/test/coverage and more.
• Use BuildBuddy Bazel remote cache capabilities
• Use Bazel binaries in Bats tests
• Nuke Nix; build Docker images using Bazel
• Refactor resiliency tests to use Bazel Docker images
• Use xlarge Linux Docker executor in CI for everything except Docker-related steps
• Run e2e Bats tests via Bazel
• Run resiliency Bats tests via Bazel
• Enable token test that was not supported by Nix
• Remove staging file duplication
• Make BATs file output TAP-compliant
• bats-assert and bats-support are now handled by Bazel

Fixes #294
Fixes #264
Fixes #265

TODO:

• Build Docker images on macos (building works, I need a system to test it on!)
• Proper Bazel transitions
• Optimizations
• DRY (macros)

@hansl I'm not 100% finished and need to merge main into this branch, but I think you can start reviewing

[hansl]

Do we want to check the SHA?

[fmorency]

SHAs are currently unavailable from the Bazelisk GitHub release page. I asked on their Slack.

[hansl]

Same as above. Also I can't remember but I think brew is installed on those machines, so just brew install bazelisk could do.

[fmorency]

It takes forever to run brew on the CI (I stopped it after 2mins) vs fetching the binary (2s).

Let's stick to the current method.
