This updates cloudkitty's requirement and setup files in order to use
openstack/requirements for constraints. This will help to avoid dependency
conflicts when cloudkitty is deployed in an openstack context.
Work items:
* Updated requirements.txt, test-requirements.txt and setup.py with the
`update-requirements` tool provided by openstack/requirements.
* Added a lower-constraints.txt file.
* Added the "check-requirements" zuul job template to the CI.
