Subject: xci: Check XCI playbooks using ansible-lint

The ansible-lint tool can help with maintaining consistency across all
the XCI playbooks, so lets introduce it early in the process to capture
common mistakes before the actual XCI deployment is executed. This
however needs to run after all the scenarios repositories have been
cloned and configured.
