Fixes LP Bug#879136 - keyerror: 'image' when doing nova image-list Fixes LP Bug#819936 - New image cache breaks Glance on Windows This patch refactors the image cache further by adding an adaptable driver layer to the cache. The existing filesystem-based driver that depended on python-xattr and conditional fstab support has been moved to /glance/image_cache/drivers/xattr.py, and a new default driver is now based on SQLite and has no special requirements. The image cache now contains a simple interface for pruning the cache. Instead of the logic being contained in /glance/image_cache/pruner.py, now the prune logic is self-contained within the ImageCache.prune() method, with pruning calling the simple well-defined driver methods of get_least_recently_accessed() and get_cache_size(). Adds a functional test case for the caching middleware and adds documentation on how to configure the image cache drivers. TODO: cache-manage middleware...
