Armando Migliaccio e354599134 Add agent-side driver scaffolding for trunk functionality
The agent code is enhanced to allow the trunk agent-side counterpart
to be activated seamlessly by means or local registry notifications.
Some integration with the server side is provided by loading the
RPC agent-side skeleton. Basic unit testing provides some coverage.

More effective functional and system coverage will be provided once
everything comes together.

Partially-implements: blueprint vlan-aware-vms
