create listener saves the listener info (in the omap) without the default values

[gadididi]

I created listener not via the cli.
according to the proto file, some fields are "optional" , means there are default value.
e.g. for "adrfam" field, the point is if adrfam was not provided, it took the default (ipv4)
then the MessageToJson function convert the request to json, but it ignore the default fields .

in this section on the code:

if context:
    # Update gateway state
    try:
        json_req = json_format.MessageToJson(
            request, preserving_proto_field_name=True,
            including_default_value_fields=True)
        self.logger.info(f"create_listener json_req: {json_req}")
        self.gateway_state.add_listener(request.nqn,
                                        request.host_name,
                                        "TCP", request.traddr,
                                        request.trsvcid, json_req)

after listener seemingly created:

I ran listener list:

No listeners for nqn.2016-06.io.ceph:subsystem.test-integration

and from the log:

maybe need to check in all places there are optional filed and using MessageToJson
