QPID-3603: Separate QueueGuard from ReplicatingSubscription.

QueueGuard: implements QueueObserver to delay completion of new messages.
ReplicatingSubscription: Implements subscription, sends messages & events to backup.

These were previously combined as one. QueueGuard is now separated out
so that it can be created before the ReplicatingSubscription, in
anticipation of an expected backup connecting. This is needed for 2 reasons:
- new queues must be guarded until they are backuped up.
- after a failover, all queues must be guarded until backups are ready.

QPID-3603: Introduced RemoteBackup to track backup status.

The primary creates RemoteBackup object for each connected or expected
backup. On first being promoted, the new primary has a RemoteBackup
for each of the known backups at the time of the failure.

The RemoteBackup manages queue guards for its backup and
tracks it's readiness.

QPID-3603: Move calls to ConfigurationObserver outside of locks.

QPID-3603: Guard should not complete messages from the internal event queue.

ReplicatingSubscription::acknowledge was calling Guard::complete for messages on the
internal event queue as well as the replicated queue. Corrected to only complete
messages from the replicated queue.

QPID-3603: HA bug fixes around transition to ready status

- Simplify QueueGuard::firstSafe calculation.
- Fix error in setting initial queues - was not checking if replicated.
- Send ready status to backups. Tests hang, deadlock in opened()->RemoteBackup on primary?
- Fix deadlock in QueueGuard.
- Don't start guards inside ConnectionObserver::opened.
