[eventlet-deprecation][WSGI] Missing periodic workers when using WSGI server

[Rodolfo Alonso]

Since [1], the Neutron API spawns a periodic worker [2] that is used to remove the expired reservations. This is used by the quota driver ``DbQuotaNoLockDriver`` (the default one).

When using WSGI, this worker is not launched.

    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.

    Add a new process to spawn the plugin services in the Neutron server

    When using the Neutron WSGI module, the plugin services (periodic
    workers created on demand in the ML2 plugin initialization) were not
    spawned.

    This patch adds a new service that should be spawned within the Neutron
    API processes, similar to the RPC server.

    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.
