Currently, the airship-shipyard-ubuntu job deploys K8s using outdated
playbooks. The job fails due to a change  that introduced an AppArmor
requirement to Calico. This change removes the failing job, as its
success does not depend on changes in Shipyard.
In the future, jobs requiring K8s should be deployed using the new
Minikube gate scripts from the OpenStack-Helm infra repository. They
will be added in future changes once they are required. Additionally, a
future change will introduce a Helm linting gate for charts hosted in
the Shipyard repository.
