In preparation for dynamic clustering support:
- Added Cluster metadata service and metadata store interfaces
- Added a static cluster metadata store implementation that is backed by a local file.
- Consolidated the existing cluster.json and tablets.json metadata files into a single cluster.json file that has all the cluster related metadata.
- Removed dependency on ONOS_NIC env variable.
