rabbitmq: updated to 3.9.13

RabbitMQ 3.9.13

Core Server

Bug Fixes

Disk space monitor now correctly parses output on (at least some) systems where non-ASCII characters are used in paths.

Stream leader election is now deterministic when cluster is undergoing a rolling upgrade.

Enhancements

Queue and binding definition import can be delayed until a moment
when at least N nodes (e.g. three) have joined the cluster. This way imported quorum queues will have a desired
number of replicas from the start.
