[maureensturgeon]

Adds some logging of events to New Relic so that we can get a better sense of how our teacher dashboard progress table is performing.

The logs in the console represent events that will be reported to New Relic:

Testing story

I plan on taking a look in New Relic once these changes are released to figure out if the reporting that I've added is enough or if we need more information. It wouldn't surprise me if we need to do some follow-up work to add more reporting or more specific data.
