Cannot delete all queued images from cache when using xattr driver

[Paul Bourke]

Deleting all queued images is broken when using caching with the xattr driver, due to a missing get_cache_files function:

"""
$ glance-cache-manage --force delete-all-queued-images
Failed to Delete all queued images. Got error:
The request returned 500 Internal Server Error.
"""

    Fix cache delete-all-queued-images for xattr

    Deleting all queued images was broken when using caching with the xattr
    driver, due to a missing get_cache_files function.

    The missing function can be satisfied by substituting the call to
    get_cache_files() with get_all_regular_files()

    Fixes bug 1197402
