[Openstack] Swift: not existing objects in container list

Hi Jan,

When expiring objects are still showing in listings they are not really
deleted by object-expirer yet - the object-server lies rather than serve a
file with a x-delete-at header in the past.

Its likely that your expirer is stuck on an object name and not proceeding
past that name, there are a few different unicode related bugs in previous
versions of swift.

Check out what the expiring objects container looks like, I do this with a
command like: swiftly --direct=/v1/.expiring_objects

The containers are each unix timestamps corresponding to a particular hour,
each container has object names for those files which need deleted in that
time period. You can see if you have old containers which have got stuck,
and what the object names are. Its usually quite obvious. You can delete
