As the Pecan server only server REST requests over HTTP, this patch introduces a new server implementing the RPC over AMQP endpoints for agent/server communication. However, the REST server does not yet have the ability to send notifications to the RPC server or directly to the agents. This patch simply adapts the ML2 plugin to run the RPC notifiers only when initialized in the pecan server, so that notification to agents can still be sent. This patch therefore is tantamount to a poor man's implementation of REST/RPC separation which will be iteratively improved. Change-Id: Ie471869d9b2793acdc412f13507038433f6a72c6
