This patch adds mostly blackbox health checks using the Openstack component APIs (neutron, nova) and creating a workload and checking connectivity to it. To implement in next patches: - Health checks using Openshift client (pods status) - Connect to EDPM nodes and verify they are healthy Change-Id: I412cb9933c4cdd2662561fafcfc1c18fceccc0c3
