      Hide
      ConnectionImplementation now uses asynchronous connections to zookeeper via ZKAsyncRegistry to get cluster id, master address, meta region location, etc.
      Since ZKAsyncRegistry uses curator framework, this change purges a lot of zookeeper dependencies in hbase-client.
      Now hbase-client only depends on only ZKAsyncRegistry, ZNodePaths and the newly introduced ZKMetadata.
