Description

(From a TODO)

The RegionServers send reports of sizes from to the Master so the Master can compute the "size" of each Table.

Presently, the Master has no way to expire these reports. Thus, reports for tables that are deleted would be retained in memory. Retain the time at which the report was received by the master, and then use that to determine when to age it off.
