    Temporarily use tempest master for all builds and fix configs

    A fix [1] was introduced in openstack-ansible to use tempest from
    the master branch in the AIO, but respecting the installation
    from PyPI everywhere else. This allowed users to chose
    the appropriate behaviour for their use cases.

    This patch [1] also made sure we didn't have anything else to do
    when the patch would land on stable branches, as this would
    automatically get disabled.

    However, as of today, there is still no new version of tempest,
    and our stable/rocky branch has been cut. Therefore the fix that
    was in place is useless and another approach needs to be
    taken.

    We will move to use tempest master for master and stable/rocky
    branch until the fix that caused this series of patch to
    happen is released [2] for tempest on PyPI.

    A temporary workaround was also added to ensure ceph can still
    be built, by freezing the ceph-ansible role sha.

    The checksum fill option, was useful a long time ago, but at this point
    its just some lovely technical debt that we carry around like an old
    dirty security blanket. This change sets us free from the sins of our
    past.

    We seem to have a lot of jobs that timeout but seem to be very
    close to completing, so let's bump the timeout by 20 minutes.

    To make up for it, we drop most of our non-voting jobs because
    they are taking up resources and always failing. This should
    decrease the amount of resources we're consuming.

    Also, instances are failing to launch when jobs hit any nodepool
    VMs inside OVH.
