Now the ML2 core plugin maps driver errors to MechanismDriverError
and hides the error details from the caller.
This patch change MechanismDriverError from an instance of
NeutronException to an instance of MultipleExceptions. Add add
exceptions from mechanism driver as inner_exceptions of
MultipleExceptions. As a result, the api layer will unwrap the
MechanismDriverError and return the real error to client.
