Description

To clarify the usage of ClusterStatus API.

1. It makes no sense that user want to create custom ClusterStatus; As a result, we should declare the builder of ClusterStatus as IA.Private.
2. HBASE-6038 removed the write/readFields from ClusterStatus; thus the Writable is meaningless for ClusterStatus now.
