Public bug reported:

An issue arises if an cached image is manually deleted (rm -rf) from the
image-cache directory, but not removed from the sqlite db, causing the
glance-cache-pruner to fail to prune:

2014-02-28 16:42:11.454 28527 INFO glance.image_cache [-] Image cache loaded driver 'sqlite'.
2014-02-28 16:42:11.460 28527 DEBUG glance.image_cache [-] Image cache currently 117893357067 bytes over max size. Starting prune to max size of 322122547200  prune /opt/glance/lib/python2.6/site-packages/glance/image_cache/__init__.py:182
2014-02-28 16:42:11.463 28527 CRITICAL glance [-] [Errno 2] No such file or directory: '/var/lib/glance/image-cache/af98e031-168b-4bd5-99b2-ab184c422c42'

If the file does not exist, it would be nice to gracefully handle this
missing image problem and remove it from the cache db, rather than
failing to prune anything.
