Add v2 cluster registration api to k8s orchestrator
Adds orchestrator API support for creating cluster-providers, registering clusters and their kubeconfig, adding labels to cluster and key value paisr to clusters. See: https://wiki.onap.org/display/DW/V2+API+Specification#V2APISpecification-ClusterRegistrationAPI Issue-ID: MULTICLOUD-922 Signed-off-by: Eric Multanen <eric.w.multanen@intel.com> Change-Id: I775a308e9ffb19acf65cb0e5752705998bc5b659
