The RabbitMQ variable `rabbitmq-ha-promote-on-shutdown` now defaults to
`"always"`. This only has an effect if
`om_enable_rabbitmq_high_availability` is set to `True`. When
`ha-promote-on-shutdown` is set to `always`, queue mirrors are promted on
shutdown even if they aren't fully synced. This means that value
availability over the risk of losing some messages. Note that the contents
of the RabbitMQ definitions.json are now changed, meaning RabbitMQ
containers will be restarted on next deploy/upgrade.
