Make Actors event-agnostic

Removed event and event-context code from the Actor code.  Also removed
the preprocessing steps from the Actor code, giving the application
complete control over any preprocessing.
Also fixed a bug wherein the APPC actor was treating the
AAI_RESOURCE_VNF property as a String instead of as a GenericVnf.
