In a recent management server crash, it was found that the largest contributor
to memory leak was in VmwareContextPool where a registry is held (arraylist)
that grows indefinitely. The list itself is not used anywhere or consumed. There
exists a hashmap (pool) that returns a list of contexts for existing poolkey
(address/username) that is used instead.
This fixes the issue by removing the arraylist registry, and limiting the
length of the context list for a given poolkey.

The managed context framework provides a simple way to add logic
to ACS at the various entry points of the system. As threads are
launched and ran listeners can be registered for onEntry or onLeave
of the managed context. This framework will be used specifically
to handle DB transaction checking and setting up the CallContext.
This framework is need to transition away from ACS custom AOP to
Spring AOP.
