Cluster distributed data store
Add experimental cluster co-ordination service using Atomic framework. Included distributed data store creation utilities. Sample docker compose data cluster between cds controller and resource-resolution instances. Issue-ID: CCSDK-2000 Signed-off-by: Brinda Santh <bs2796@att.com> Change-Id: I4de00e773a996e08fd1d260fc27ed18832433883
