"TestNeutronServer" related tests failing frequently

[Rodolfo Alonso]

"TestNeutronServer" and those inheriting from this parent class ("TestWsgiServer", "TestRPCServer", "TestPluginWorker") are failing frequently.

    Switch neutron-rally-task job to ML2/OVS and skip "test_models_sync"

    After switch of the default Neutron backend to the ML2/OVN
    in the Devstack we had 2 rally jobs running actually with the
    same Neutron backend.

    This patch configures explicitly ML2/OVS as a backend in the
    'neutron-rally-task' job so it is like it was before the change in
    the Devstack repo.

    In order to fix the CI, this patch also skips "test_models_sync" test
    cases. Once [1] is fixed and released, we'll be able to create SQL
    tables specifying the "_constraints_included" flag. When creating a
    table, this flag should be set to "False" in order to be able to set
    the "index" and "unique" parameters for each column in the table
    definition, as we do now.

    "test_update_router_admin_state" is excluded from
    "neutron-ovn-tempest-slow" until LP#1890445 is fixed.

    Set "test_restart_wsgi_on_sighup_multiple_workers" as unstable.

    CI job "neutron-ovn-tempest-slow" has been set to non-voting until
    LP#1930402 is fixed.

    Use "multiprocessing.Queue" for "TestNeutronServer" related tests

    Instead of using a file to log the processes status and actions,
    "TestNeutronServer" now uses a "multiprocessing.Queue" that is
    safer than writting a single file accross multiple processes.
