See discussion in #608.

  • Add a remove method to IQueueRepository, so queues can actually be removed when no longer needed.
  • Make the Session the only place where the Queue lives outside of the repository by removing the queues field from SessionRegistry.
  • Tie a Queue and a Session in a 1-to-1 way.
  • Remove and clean the old Session and Queue before creating a new pair for a ClientId.
  • Clean Session and Queue when they are no longer needed.
  • In case a new Connection takes over a Session from an existing, connected connection, ensure the old session can not influence the Session any more after the Session was taken over.

Added interface for removing queues from repositories

@hylkevds
Reworked session and queue creation
699e40a 
Only one queue per clientId can exist. Don't create a new session/queue
unless it is certain we need a new session, and make sure the old session
/queue is cleaned up first.

@hylkevds we are almost there, just a couple of nitpick and the PR then is ready.

Excellent. They should all be fixed now.
