Change ClusterMap API object to support multiple kubeconfig sources for a cluster. If one kubeconfig source fails, kubeconfig builder will not fail and move on to the next one. This behaviour will allow to support cases when ephemeral cluster is not accesible anymore or when target cluster is not yet accessible. For more information please read issue #460 in airshipctl github Relates-To: #460 Related-To: #460 Change-Id: I7cd32f78cd7c4ad8814eac357424c24216f40d76
