Also rework elixir dependency handling, so we no longer rely on mix to
fetch the rabbitmq_cli deps
Also:
- Specify ra version with a commit rather than a branch
- Fixup compilation options for erlang 23
- Add missing ra reference in MODULE.bazel
- Add missing flag in oci.yaml
- Reduce bazel rbe jobs to try to save memory
- Use bazel built erlang for erlang git master tests
- Use the same cache for all the workflows but windows
- Avoid using `mix local.hex --force` in elixir rules
- Fetching seems blocked in CI, and this should reduce hex api usage in
all builds, which is always nice
- Remove xref and dialyze tags since rules_erlang 3 includes them in
the defaults
bazel-erlang has been renamed rules_erlang. v2 is a substantial
refactor that brings Windows support. While this alone isn't enough to
run all rabbitmq-server suites on windows, one can at least now start
the broker (bazel run broker) and run the tests that do not start a
background broker process
Unlike with gnu make, mixed version testing with bazel uses a package-generic-unix for the secondary umbrella rather than the source. This brings the benefit of being able to mixed version test releases built with older erlang versions (even though all nodes will run under the single version given to bazel)
This introduces new test labels, adding a `-mixed` suffix for every existing test. They can be skipped if necessary with `--test_tag_filters` (see the github actions workflow for an example)
As part of the change, it is now possible to run an old release of rabbit with rabbitmq_run rule, such as:
`bazel run @rabbitmq-server-generic-unix-3.8.17//:rabbitmq-run run-broker`
Adds WORKSPACE.bazel, BUILD.bazel & *.bzl files for partial build & test with Bazel. Introduces a build-time dependency on https://github.com/rabbitmq/bazel-erlang
