Update jobs

Remove tox-linters job, the default job now runs on bionic, so there's
no need to use an extra job. Replace it with the default job.

Replace obsolete build-openstack-sphinx-docs with new template
build-openstack-docs-pti which calls "tox -e docs" directly.
Update tox.ini for this to use python3.

Fix URL in docs to use new location of repo after OpenDev rename.
