This diff introduces the following updates to the protobuf file:
- newNotifyTokenRequired of oneof protobuf request to the client to request the new notification token from the client.
- An optional newNotifyToken field to get the new notification token from the client.
In case of the client has an expired or wrong notification token we will send a newNotifyTokenRequired message to the client and will expect that he will re-request the Get gRPC request with the newNotifyToken and the token will be updated in the database.
