upgrade:
- Set RabbitMQ ``cluster_partition_handling`` to ``pause_minority``.
This is to avoid split-brain.
The setting is overridable using custom config.
Note this new config requires at least 3-node RabbitMQ cluster
to provide HA (High Availability).
See production architecture guide for more info.
