Create a utility that can convert Obojobo events into corresponding Caliper events on demand.

[FrenjaminBanklin]

Obojobo will currently create Caliper events matching Obojobo events as those events occur, writing all of the necessary data into the various relevant tables and also writing a row into the caliper_store table after processing an event or Express request object through this code and, if the event has a corresponding Express request, this code.

Currently this data is not being used, and is in fact causing significant database bloat. Instead, it would be nice to have a convert_obojobo_event_to_caliper_event utility that could convert existing Obojobo events into Caliper events on demand instead of maintaining a costly database table that potentially goes unused.

For example, something like this might live in packages/app/obojobo-express/bin/convert_obo_event_to_caliper_event.
