    Disable the OVN/OVS WGSI experimental jobs

    The following jobs have been disabled:
    * neutron-tempest-plugin-api-ovs-wsgi
    * neutron-tempest-plugin-api-ovn-wsgi

    Once [1] is merged, all ML2/OVS and ML2/OVN jobs will be executed
    with WSGI module. These jobs will be converted to *-eventlet and
    will be in the experimental and periodic queues.

    Do not define the executor of the RPC server

    The method ``oslo_messaging.get_rpc_server`` allows to define the
    executor between "eventlet" and "threading".

    By default the server class used is
    ``oslo_messaging.rpc.server.RPCServer`` [1]. If no executor is defined,
    the base class will get it depending on the context [2][3]. If
    ``thread`` is not monkey patched, the executor to use will be
    "threading".

    Make grenade jobs work with Neutron API WSGI module

    The "skip-level" jobs, that work with 2024.1 (two releases back),
    cannot yet work with WSGI because:
    * For ML2/OVS it was refactored and fixed in 2024.2
    * For ML2/OVN it was implemented in 2024.2

    We'll need to wait until 2025.2 to provide this support and remove
    the WSGI flag from the devstack libraries (check [1]).

    Move grenade skip level jobs to wsgi

    With [1] we can't deploy neutron with eventlet in
    master and wsgi is default mode[2], so let's switch
    grenade skip level jobs to deploy with wsgi.
    Just dropped the overrides as parent grenade jobs have these
    already set.
