    Fix multiple CI issues

    1. Pin openstacksdk and client libraries in kolla-toolbox

    Stein and below only.

    openstacksdk released 0.45.0 (and possibly 0.44.0 as well) which dropped
    py2 compat but did not advertise the fact. It was amended later but it
    will now always affect kolla images until pinned to older.

    The observable error is:
    "ImportError: No module named queue"

    Since Train we pin u-c, but not before that.

    This change introduces a version constraint for openstacksdk and client
    libs:

    - python-novaclient
    - python-cinderclient
    - python-keystoneclient
    - python-glanceclient

    2. Make deploy jobs non-voting

    For similar reasons to 1., the deploy jobs fail when using the openstack
    client for testing. Due to a dependency loop between these two projects,
    we must make these jobs non-voting to fix the image build. This should
    be reverted ASAP.

    3. CI: Add https match for mirror.centos.org to template-overrides

    Some CentOS repos (currently one - Ceph NFS Ganesha) use
    https://mirror.centos.org instead of http:// and we break
    their definition by removing mirrorlist= entry and not inserting baseurl
    entry due to a missing match.

    (cherry picked from commit 4d11cd647a12ec900059f1cb53b30ad2b0fb22ab)

Can confirm this fix works fine for stein.

This issue was fixed in the openstack/kolla rocky-eol release.
