The requirements repo is support python 3.5 as oldest python version
while swift still supports py27.
thus, requirements-check will fail on a couple of lines in swift. The
check is only run when these files are touched.
The py2.7 packagers we know about aren't depending on upstream
requirements.txt for correctness and aside from all the production
deployments running on py2.7 we only realistically support >=py3.7
There's no good reason for our requirements.txt to be "unspported" by
the openstack requirements check job. Since they only support >=py3.5
we can change our requirements.txt inline with that. This should be
fine for everything we could hope to get out of both our
requirements.txt and the check!
