src: add user session detection implementation

Detect user login and logout for Linux and Windows.

Report an active interactive session through the /refresh response
so a new ogserver instance can update the session status.

Poll the session change in 5 second intervals in a thread. Use the
same event socket previously used by the old session detection
mechanism to notify a session change.

Use the method check_interactive_session_change in each
ogOperations.py to report the session status.
Return values:
	None: no session changes are found
	True: login
	False: logout

Windows
Verify if psutil.users() has any value.

Linux
Verify all the psutil.users() asociated to a terminal.
