Set the Neutron server workers name

The patch [1] defines the RpcWorker and RpcReportsWorker processes
names. However, the parent class ``neutron_lib.worker.BaseWorker``
init method is not reading the class variable defined in [1]. This
patch is explictly passing the ``desc`` class name in the init method.
