Simon Willnauer f128b7a7fe Improve connection closing in RemoteClusterConnection (#22804)
Some tests verify that all connection have been closed but due to the
async / concurrent nature of `RemoteClusterConnection` there are situations
where we notify listeners that trigger tests to finish before we actually
closed all connections. The race is very very small and has no impact on the
code correctness. This commit documents and improves the way we close
connections to ensure test won't fail with false positives.
