Details

Summary

This diff introduces handling by the gRPC server of the NewNotifyToken message message from the client in the MessagesStream bidirectional stream.

When the client sends the new notification token the server should save it for the client in the database sessions table.

Linear task: ENG-2060

Test Plan

Connect to the bidirectional gRPC MessagesStream stream with the valid sessionID in metadata and send the message to the server with the NewNotifyToken field value as a random string.
The expected behavior is that the value will be written into the sessions table of the dynamoDB database into the NotifyToken field.

This should be the actual error because in this case, something is wrong with the database, but I agree that we should use tracing instead.
I've made changes to use error! from tracing where errors should be raised.

Shouldn't we somehow inform the client that an attempt to set a token failed?

Makes sense to return an internal error to the client. I've added returning of the gRPC Internal error in this case. Thanks, @tomek!
