Subject: [PATCH] Allow to call the discover-latest-image role

It comes from oooq-extras:
https://opendev.org/openstack/tripleo-quickstart-extras/src/branch/master/roles/discover-latest-image

Calling it will allow to correct some issues we may face when the image
changes on a daily basis.

It adds 3 new parameters:
+tripleo_ci_discover_latest (boolean): whether or not discover latest
image
+tripleo_ci_discover_base_url: base_url passed down to the role
+tripleo_ci_discover_qcow_prefix: qcow_prefix passed down to the role

Depends-On: https://review.opendev.org/c/openstack/tripleo-quickstart-extras/+/871833
