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.
