QPID-4401: Revert: HA bindings for QMF exchanges not replicated.
This reverts r1403946: There was a problem with this, for example if I bind a
queue Q to receive broker events. On the backup, Q will receive double events:
from the replicating subscription to the primary and events generated locally in
the backup broker. That can cause the backup to generate "invalid position"
errors and shut down.
