/**
* Part 1: Simple test of TTL. Create a new collection with 24 docs, with timestamps at one hour
* intervals, from now-minus-23 hours ago until now. Also add some docs with non-date
* values. Then create a TTL index that expires all docs older than ~5.5 hours (20000
* seconds). Wait 70 seconds (TTL monitor runs every 60) and check that 18 docs deleted.
* Part 2: Add a second TTL index on an identical field. The second index expires docs older than
* ~2.8 hours (10000 seconds). Wait 70 seconds and check that 3 more docs deleted.
