This is similar to #391 but introduces a similar command for classic mirrored queues:

rabbitmq-queues check_if_node_is_mirror_sync_critical

This check would fail if the target node hosts one or more classic mirrored queues (masters) that have no online in sync mirrors.

Part two of #389.

Test procedure:

Start 3 node cluster
Create HA policy applied to all queues ha-mode = exactly, ha-args = 2
Create three queues, each having a master on a different node.
Run this new command, everything is A-OK
Stop two nodes. Command will return an error stating that no synchronized mirrors exist for the three queues.
