Arnaud Morin 8e3c523fd7 Auto-delete the failed quorum rabbit queues
When rabbit is failing for a specific quorum queue, the only thing to
do is to delete the queue (as per rabbit doc, see [1]).

So, to avoid the RPC service to be broken until an operator eventually
do a manual fix on it, catch any INTERNAL ERROR (code 541) and trigger
the deletion of the failed queues under those conditions.
So on next queue declare (triggered from various retries), the queue
will be created again and the service will recover by itself.

Auto-delete the failed quorum rabbit queues.
When rabbit is failing for a specific quorum queue, delete the queue
before trying to recreate it.
This may happen if the queue is not recoverable on rabbit side.
See https://www.rabbitmq.com/quorum-queues.html#availability for more
info on this specific case.
