QPID-5421: Refactor: clean up QueueObservers.

Refactor of queue observers to use the broker::Observers base class. Simplifies Queue code
and makes it more consistent with other observers (BrokerObservers, ConnectionObservers.)

Modified Observers base class to allow identical locking behaviour to previous
impementation.

> When using standalone replication between two brokers, there will be replication errors if messages are put onto the primary queue before replication is set up.
> To reproduce:
> Create queue "q" on brokers P and B.
> Put messages 1,2,3 on P.q
> Start replication from P.q to B.q
> Put messages 4,5,6 o P.q
> Fetch and acknowledged one message from P.q
> Fetch all messages from B.q. Instead of the expected messages [1,2,3,4,5], q has [0,1,3,4,5]
