REST API for pseudowire addition / deletion.
Refactored pseudowire code to use REST in order
to add or delete pseudowires individually. Previous implementation
used the network configuration, which is now completely
removed from the code. Further, I re-organized the code
and create a utility class that holds all the necessary
functionality for verifying pseudowires.
Further, I removed all mastership checks in the pw code
since now a specific pseudowire creation is sent to a single
instance, which will handle the call.
