QPID-4327: HA TX transactions: basic replication.
On primary a PrimaryTxObserver observes a transaction's TxBuffer and generates
transaction events on a tx-replication-queue. On the backup a TxReplicator
receives the events and constructs a TxBuffer equivalent to the one in the
primary.
Unfinished:
- Primary does not wait for backups to prepare() before committing.
- All connected backups are assumed to be in the transaction, there are race
conditions around brokers joining/leavinv where this assumption is invalid.
- Need more tests.
> HA support for TX transactions.
