2022.3: socket.send on msg_out_event_handler crashed

[viniarck]

This has been caught in prod on May 22, 2024:

<Task finished name='Task-7' coro=<Controller.msg_out_event_handler() done, defined at /usr/local/lib/python3.9/dist-packages/kytos/core/controller.py:607> exception=DeprecationWarning("Using sendall() method on sockets returned from get_extra_info('socket') will be prohibited in asyncio 3.9.

However this part has been refactored and this warning has been mitigated on recent PRs when python was upgraded to 11, following std lib docs. Nevertheless, I'll leave this issue open, let's try to exercise switches connection/disconnection more.
