Description

There should be a RocksDB instance in Nimbus where we write metrics from the heartbeats. This should allow us to replace storage for the statistics we see in the UI and expand the abilities of UIs to allow for time series charting.

Eventually this data will likely come via thrift to Nimbus as the overall metric system is overhauled.
