The container-reconciler and object-expirer were missing from the os-swift
role. The reconciler makes sure incorrectly placed objets live in the
correct storage policy. The expirer is the service that deletes expired objects.
This change also adds the abilty to optionally specify a reclaim_age in the swift
section of the configuration, which is now set in all the locations required,
still with the default of 604800 seconds (7 days).
