Subject [19/49] hbase git commit: HBASE-17428 Implement informational RPCs for space quotas
Date Mon, 22 May 2017 20:07:15 GMT
HBASE-17428 Implement informational RPCs for space quotas

Create some RPCs that can expose the in-memory state that the
RegionServers and Master hold to drive the space quota "state machine".
Then, create some hbase shell commands to interact with those.
