This patch rehomes neutron.worker.NeutronWorker as neutron_lib.worker.BaseWorker. While this class is only used by networking-ovn out of the neutron tree today [1], the ML2 MechanismDriver (publically extendable) supports workers directly [2] (ex: get_workers()). As a result the worker is part of our publicly extendable API and thus seems a likely candidate for neutron-lib. UTs and a release note are also included.
