    port_forwarding: extend support for OVN usage (cont.)

    This is a follow up from commit 102c442bcfa39074787e3292818880ecf238ac61

    The call to resources_rpc.ResourcesPushRpcApi() will fail in situations
    where RPC is not available. That is the case for neutron_ovn_db_sync_util.

    The changes here will only set push_api if any of the configured service
    plugins need it. This is a behavior similar to what is done for the QOS
    plugin.
