When scaling down pods it is possible for transactions to remain in their prepared state, we need to support the ability to recover these transactions and either commit or rollback the transaction.

We can use the approach already used within A-MQ to migrate messages on scale down, this allows an associated container to recover the transactions and attempt to complete them.

Note that this is not intended to address scaling down of servers with subordinate transactions (e.g. JTS or JBoss Remoting) as per ~~CLOUD-2262~~ that is not yet tested or supported.
