Force peer validity check for BGP peer.

Extend the Peer class to specify if a validity check for peer
is needed whenver it is enqueued as a key paramater for DB request.
Currently BGP peer derived class falls into this category.
Any agent route data enqueued with BGP peer in key will have to
implement validity check.

Also remove NULL peer usages in agent key from test cases.
