Various bug fixes to make stream coordinator membership changes more reliable. Previously various errors could happen as well as partially successful attempts where the membership change command may fail but it leaves the new server running. Also ensure that stream coordinator members are removed as part of the forget_cluster_node command. Add stream coordinator status command. To show the raft status of the stream coordinator just like is done for quorum queues.

Don't do clustering with mixed versions anyway. Please.
Also refactor to avoid double read of queue record.
And fix a race condition flake in amqp10_client_SUITE.

Various bug fixes to make stream coordinator membership changes more reliable. Previously various errors could happen as well as partially successful attempts where the membership change command may fail but it leaves the new server running.
Also ensure that stream coordinator members are removed as part of the
forget_cluster_nodecommand.Also added
rabbitmq-streams coordinator_statuscommand so that we can get a view of replication and other information in a nice tabular format, same asrabbitmq-queues quorum_statusThis PR also contains a change to allow
rabbit_nodes:list_member/0to return[](rather than[node()]) when the query to fetch the current members fails. This allows us to detect this scenario in the code and avoid, e.g. shrinking the coordinator cluster incorrectly.Also adding back a missing clause in the quorum queue tick handler that was accidentally removed in #10364
