Allow offloading lookups in driver contexts

Browse Source 
This allows segments looked up ahead of time to be passed
into NetworkContext objects and NetworkContext objects to
be passed into PortContext objects. This allows us to avoid
doing segments lookups for every PortContext construction
when handling a bunch of ports (e.g. in RPC handler).
