Comment 9 for bug 1404983

Pavlo:
juno requirements for heat tell, that:
requests>=1.2.1,!=2.4.0 (https://github.com/openstack/heat/blob/stable/juno/requirements.txt#L36)
so it is possible to use new versions of "requests" library.

Also urllib3: is not mentioned in juno requirements (not for Heat, not in global-requirements).
It appeared only in master branch of global requirements:
urllib3>=1.8.3 ( https://github.com/openstack/requirements/blob/master/global-requirements.txt#L154)
