Test case rabbit_mqtt_qos0_queue_kill_node flaked because after an
MQTT client subscribes on node 0, RabbitMQ returns success
and replicated the new binding to node 0 and node 1, but not
yet to node 2. Another MQTT client then publishes on node 2
without the binding being present yet on node 2, and the
message therefore isn't routed.
This commit attempts to eliminate this flake.
It adds a function to rabbit_ct_broker_helpers which waits until a given
node has caught up with the leader node.
We can reuse that function in future to eliminate more test flakes.
Bazel build files are now maintained primarily with `bazel run
gazelle`. This will analyze and merge changes into the build files as
necessitated by certain code changes (e.g. the introduction of new
modules).
In some cases there hints to gazelle in the build files, such as `#
gazelle:erlang...` or `# keep` comments. xref checks on plugins that
depend on the cli are a good example.
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
