    Multiple fixes to unblock CI

    This change includes a number of fixes to make CI functional.

    * Blacklist ansible 2.8.9 in kolla-toolbox

      Ansible 2.8.9 broke the OpenStack modules, see
      https://bugs.launchpad.net/kolla/+bug/1866181 for details.

      This causes us to fail with the following error:

        /usr/lib64/python2.7/distutils/version.py\", line 40, in __init__
        self.parse(vstring)
        File "/usr/lib64/python2.7/distutils/version.py", line 105, in parse
        match = self.version_re.match(vstring)\nTypeError: expected string or buffer

      This change works around the issue by blacklisting ansible 2.8.9 in
      the kolla-toolbox image.

    * Drop CentOS 7 CI jobs. There are multiple issues with CentOS 7 now,
      and we have CentOS 8 jobs in place so it's time to move on

    * pin requirements to commit
      ea42244642c3c091cb4f70917ae8d79af217b6af. This is required to avoid
      oslo.cache 2.1.0, which breaks us. See
      https://bugs.launchpad.net/kolla-ansible/+bug/1866008.
