urllib3 version incompatible with requests 2.26.0

Bug:
Requests 2.26.0 only requires 'urllib3>=1.21.1,<1.27' in its dependencies, but 'urllib3 >= 1.25' is necessary. When running the setup scripts, urllib3 1.22 is installed. This version meets the dependency requirements, but is incompatible.

Fix:
Upgrade urllib3 inside of the docker container and restart docker container. See README_WSUV.md on the Autolab dev branch for further instructions.
