Apply refactored NetworkFactory.

Make NetworkFactory a concrete class and divide responsibilites between it and NetworkAgent.
Factory will track requests and by default give a single connect/disconnect api for ease
of use.  Then NetworkAgent is created and destroyed as needed with very simple logic.
