(Continues where #2883 left off)

Timing / resource usage summary

• "3 hours 8 minutes of worker node usage, plus 28 minutes idle" ("idle" = node allocated but no tasks running there)
• For each category (completed task IDs / incomplete task IDs / failures), show min/max runtime.

Time chart

• Perhaps like the chrome debug panel's view of network activity (attached screen shot), but more compact.
• Or, perhaps a vertical view with y=time(down), x=node -- i.e., idle nodes show up as empty areas.

Live updates

• Subscribe to job UUID via websocket. Update charts, statistics, and log messages as logs arrive.

Testing

• Write a crunch script and a 1-component pipeline to exercises various features
  • Request >1 node and make 1st task sleep a few seconds, to ensure some idle node time
  • Run multiple tasks per node and produce stderr every few seconds, to exhibit "sort by task" behavior and usability

Other

• Add tooltips with more detail about exactly what the categories mean
