Compose: ValueError: Timeout value connect was Timeout(connect=None, read=None, total=None), but it must be an int, float or None.

[scobb]

I realize this looks like a dupe (https://github.com/docker/compose/issues/634), but the issue resurfaced with newest urllib3 and newest requests.

>pip freeze
...
docker==2.3.0
docker-pycreds==0.2.1
...
requests==2.18.0
requests-oauthlib==0.8.0
requests-toolbelt==0.7.1
...
urllib3==1.21.1
...

Running python 2.7.10 on Windows 10.

Full stack trace:
