Comment 3 for bug 1927977

There changeset [1] tackles it for a specific case (RpcWorker for sriovnicswitch).
But other plugins or extensions may need it too, so my idea would be to add configuration options like enable_ovn_idl_for_allservices_worker and enable_ovn_idl_for_rpc_workers and if they are set, enable the IDL for neutron.service.AllServicesNeutronWorker and neutron.service.RpcWorker respectively. This could be combined with [1], so that it won't be necessary to set enable_ovn_idl_for_rpc_workers explicitly for sriovnicswitch.
