QPID-6476 : Expose vhost target size so a store can decide to flow messages to 
disk in recovery if necessary

> [Java Broker] Refactor MessageStore to allow more efficient implementations

> The current MessageStore interface forces MessageStore implementations to 
> allow for queries/deletes based on semantic properties of records.  While 
> some query like functionality is required for the period of recovery after 
> restart, querying the store is not required in normal operation.   Delete 
> operations (such as dequeuing messages) currently only supply the semantic 
> keys (queue-id, message-id) rather than allowing the store to provide the 
> broker with a reference which can be used for later efficient deletion.
