Rename tox_venvlist

For consistency with the tox jobs, use tox_envlist instead of
tox_venvlist. See
https://docs.openstack.org/infra/zuul-jobs/jobs.html#job-tox for
definition of tox job.

All projects using tox_venvlist have been changed to use tox_envlist as
well (see dependencies). Now we can rename tox_venvlist to tox_envlist -
and then the projects can remove tox_venvlist and use only tox_envlist.
