This diff introduces changes to the bidirectional stream gRPC handler to skip session authentication checks by adding the sessions.skip_authentication config flag.
In case of the flag was provided we are skipping getting the session parameters from the database and expecting the device will be provided as metadata instead. Also, we are creating an empty SessionItem instance to provide compatibility with the following code in the handler. We are adding skipping of the changing of "Online" status for the session in case the flag is provided.
