    OK, I upmerged, and then had to upmerge again right after that.  I 
double-checked that uptimeSeconds appear in the places they should, and that I 
was able to change the log level for a worker running ExclamationTopology.

> In the UI, the Topology Page and the Component Page each make a 
> getTopologyInfoWithOpts thrift call to nimbus for executor heartbeat data. 
> Metrics from this data are then aggregated in by the UI daemon for display.
> When large topologies, with high-connectedness, are viewed in this way, the 
> load times for each page can be minutes long.  In addition, heap usage by the 
> nimbus JVM can grow substantially as data for each executor, component, & 
> stream is serialized to be sent to the UI.
