9f98029898 Gracefully handle response errors in stat trackers 
1. Check if the response is a 4xx/5xx
2. If it is, skip the append step and track a frame miss
3. If enough frame misses occur in a row, treat it as a pause

A "pause" is when a null data frame is added, which shows up as a
gap in line charts.

f0208c0a24 Add request throttling to the abstract stats tracker 
This is the best of three options

1. Users of stats trackers control polling (old method)
2. Stat tracker is stateful and has start/stop methods (like logging)
3. Stat trackers blindly throttle requests

This is the best option because it means N number of concurrent users of
a stats tracker can request polling without inundating the tracker with
redundant frames (or the network with redundant requests), but they also
don't have to coordinate amongst themselves to determine what state a
tracker should be in.

5c5e44df61 An abstract class for capturing nomad stats 
It follows the form of poll -> json parse -> append,
Where append is defined in subclasses to add data from the new frame
to long-lived rolling arrays of data.
