Add StateInfo structure synced resources
Add a StateInfo structure to the Cluster and Deployment-Intent-Group resources to keep track of the lifecycle state of these resources. Moved the appcontext id that was being kept into this structure as well. Enabled the approve state (and API) for the deployment intent group. Issue-ID: MULTICLOUD-1042 Signed-off-by: Eric Multanen <eric.w.multanen@intel.com> Change-Id: I36602d8a0658d9d6d37b8799f9a372a7d1042496
