The 3 modules use the sweeper:
AAE tree rebuild
Object expiry
Tombstone reaper

The sweeper adds support for modules to register fold jobs they would like to have scheduled.
This mechanism lets us perform a number of processing tasks on the IOPs/bandwidth needed to sweep the data.
The sweeper keeps track of which partition that needs to be scheduled and ask all partispants if they would like to join.

Object expiry:
