Cleanup running jobs

With the changed PTI doc building, this repo can now use the standard
way of building docs, use publish-openstack-docs-pti template and remove
custom jobs.

Since this repo is not co-installed, it does not need requirements and
lower-constraints - like none of the documentation projects. Remove
these.

Remove also lower-constraints tox environment and unused pip install
command from tox.ini as the default is just fine.

Remove passenv from docs environment, this is not needed with current CI
jobs anymore.
