Add timeout to requests call

[wtip]

It looks like a timeout was added to the requests calls that are used for streaming but the regular call never times out. I did a iptables -A OUTPUT -p tcp --dport 443 -j DROP and the nest api call just hung without timing out.

I think this section needs to be updated

response = self._session.request(verb, url,
                                         allow_redirects=False,
                                         data=data)
