Remove Python 2.7 support from testing and gates

Makes Python 3 the base python for all tox venvs and removes
py2 jobs from zuul.yaml.

Remaining:
- move the legacy gate jobs from openstack-zuul-jobs to the os-brick
  repo and make them py3 jobs
- adjust setup.cfg to require py3 and remove py2 requirements from
  test-requirements.txt and doc/requirements.txt

Partial-bug: #1853372
