This patch implements a replacement of the legacy rolling
upgrade test previously implemented. The job and pipeline
is defined in-repo to ensure that the keystone team has
complete control over the voting status, pipelines it is
in, etc.
The test uses the 'upgrade' tox environment in the
openstack/openstack-ansible-os_keystone repository which
executes a build of two keystone containers using the
the head of the stable branch of keystone, then upgrades
to the proposed review. The upgrade is a complete rolling
upgrade using MariaDB as a database.
