satellite/gracefulexit: implement rangedloop observer

Browse Source 
The tests are forked from the chore tests with slight adaptations for
being run against the ranged loop. I also moved a benchmark for the
database from chore_test.go to db_test.go.

The pathcollector is reused as a rangedloop.Partial.
