QPID-4144 HA broker deadlocks on broker::QueueRegistry lock and ha::Primary lock
Running tests repeatedly, the broker deadlocked with the attached stack trace.
The problem call sequences are:
1. QueueRegistry::destroy takes QueuerRegistry lock > ConfigurationObserver::queueDestroy > ha::Primary::queueDestroy takes Primary lock.
2. ConnectionObserver::opened cals Primary::opened lock> RemoteBackup>getQueues().eachQueue
This patch breaks the deadlock at both ends: QueueRegistry no longer holds the lock across the observer call and Primary does not hold the lock across eachQueue.
