Matthew Booth cb15d34cc1 Rename ImageCacheManager._list_base_images to _scan_base_images ...

The method's return value is never used, only its side-effects are
used. We rename it to reflect its actual usage, and remove the unused
return value to avoid confusion.

NOTE(mdbooth): The use of global state is a large part of what makes
ImageCacheManager hard to read. I don't mean to imply with this change
that's what should be done here, only to make it clearer to the reader
that it is what's being done currently.
