Data aggregation for shorter sample times

[stephenlienharrell]

We should explore data aggregation to get our sample times much lower.

It is my thought to keep the data-points at 5 minutes, but store average/min/max/std over 10 samples (30 second sampling).

This would only increase the data by 4x, instead of 10x.

then we could graph with the average and min/max bars to give a more complete picture on what happened on the node.

We probably want to do this on-node.

really a data reduction problem only, sampling size
