Matt Crees e13072a98d Add flag to change RabbitMQ ha-mode definition
Adds the flag `rabbitmq_ha_replica_count` to change how many different
nodes a queue should be mirrored across. If the value is not set, then
it defaults to "ha-mode":"all". This value is unset by default to avoid
any unexpected changes to the RabbitMQ definitions.json file, as that
would trigger an unexpected restart of RabbitMQ during the next deploy.

The config option `rabbitmq_ha_replica_count` is added, to allow for
changing the replication factor of mirrored queues in RabbitMQ. While the
flag is unset, the queues are mirrored across all nodes using
"ha-mode":"all". Note that this only has an effect if the flag
` om_enable_rabbitmq_high_availability` is set to `True`, as otherwise
queues are not mirrored.
