QPID-1050: Patch from Ted Ross:

1) Durability for federation links (broker-to-broker connections)
2) Improved handling of federation links:
    a) Links can be created even if the remote broker is not reachable
    b) If links are lost, re-establishment will occur using an exponential back-off algorithm
3) Durability of exchanges is now viewable through management
4) ManagementAgent API has been moved to an interface class to reduce coupling between the broker and manageable plug-ins.
5) General configuration storage capability has been added to the store/recover interface. This is used for federation links.
6) Management object-ids for durable objects are now themselves durable. 

(Note: some refactoring needed around ProtocolAccess needed to try and reduce dependencies)
