As noted in previous discussions, glance should clean its staging
directory on startup. This is important for scenarios where we
started an import operation, but failed in the middle. If, when we
recover, the image has already been deleted from the database, then
we will never remove the (potentially very large) residue from disk
in our staging directory.
This is currently a problem with web-download, but will also occur
with glance-direct once we have the non-shared distributed import
functionality merged.
