Add timeout for the connection session to expire

From http://docs.python-requests.org/en/master/user/advanced/

"Most requests to external servers should have a timeout attached,
in case the server is not responding in a timely manner. By default,
requests do not time out unless a timeout value is set explicitly.
Without a timeout, your code may hang for minutes or more."
