TUN-7373: Streaming logs override for same actor
To help accommodate web browser interactions with websockets, when a streaming logs session is requested for the same actor while already serving a session for that user in a separate request, the original request will be closed and the new request start streaming logs instead. This should help with rogue sessions holding on for too long with no client on the other side (before idle timeout or connection close).
