CI: Move off CentOS 8

Remove swift-tox-py36-centos-8-stream job entirely.

Move the following jobs to CentOS 9:

  - swift-tox-func-s3api-ceph-s3tests-tempauth
  - swift-tox-func-s3api-tests-tempauth
  - swift-multinode-rolling-upgrade, as well as the other rolling
    upgrade jobs

Remove the swift-multinode-rolling-upgrade-victoria job, as py39
support (required for CentOS 9) was not added until wallaby.
