    Limit the worker type in neutron-periodic-workers service
    
    The service "neutron-periodic-workers" is in charge of executing the
    ML2 plugin periodic workers (usually ``PeriodicWorker`` type). These
    workers have a worker_process_count=0.
    
    Before this patch, the method ``start_periodic_workers`` was also
    spawning other ML2 plugin workers, as the ML2/OVN ``MaintenanceWorker``,
    not expected to be running in this service.

Title:
  The periodic workers service should run only ``PeriodicWorker``
  instances

Status in neutron:
  Fix Released

Bug description:
  In [1], a new service was created to execute the ML2 plugin periodic
  workers. However, this is not only executing the periodic workers but
  also other plugin workers (for example, in ML2/OVN, the maintenance
  worker). Same as done in [2], the method retrieving the plugin workers
  should filter out those with worker_process_count>=1.
