Requirements
In order to add or change a Python dependency requirement of an OpenStack project, it must first be added to the openstack/requirements repository.
Add it to the 'test-requires' or 'pip-requires' files as appropriate and submit it for review.
The requirement specification should include both a lower and upper bound based on the release policy of the package.
Once the change to openstack/requirements has merged, the local pypi mirror will be updated and then the requirements file for the OpenStack project may be updated.
