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
