Changes the default value of `rabbitmq-ha-promote-on-shutdown` to `"always"`. We are seeing issues with RabbitMQ automatically recovering when nodes are restarted. https://www.rabbitmq.com/ha.html#cluster-shutdown Rather than waiting for operator interventions, it is better we allow recovery to happen, even if that means we may loose some messages. A few failed and timed out operations is better than a totaly broken cloud. This is achieved using ha-promote-on-shutdown=always. Note, when a node failure is detected, this is already the default behaviour from 3.7.5 onwards: https://www.rabbitmq.com/ha.html#promoting-unsynchronised-mirrors Related-Bug: #1954925 Change-Id: I484a81163f703fa27112df22473d657e2a9ab964
