Eventual Memory Leak from MemoryManager / SessionMiddleware

[dhe-cr]

Both MemoryManager and SessionManager house data. This will grow infinitely as currently there is no logic to clear stale sessions.

Implement code to tie a session expiration date to the session and delete out stale sessions from SessionManager & MemoryManager.

Possible Approaches:

1) Perhaps through websocket ? on websocket disconnect cleanup initiated. 2)

    session_uuid = request.cookies.get(COOKIE_NAME)
    if session.get("message_count") is None:
        session["message_count"] = 0
        await memory.create_session(session_uuid)

We can potentially tie cookie session id to the other session middleware. have a periodic cleanup process that checks session expiration and then eliminates.

Note, need to address behavior of user clicks out, comes back prior to session expiration and then hits session expiration. (receive new cookie) -- probably want to force a new session?

perhaps on landing on index always force a new session. (doesn't alleviate user leaving window open for 2 hours)

perhaps "easy" mode could be against date . initiate api endpoint called cleanup and it clears out memory beyond that date.
