You say refactored: What, besides the name, did you change and why?

does this always have to by a disk type? It can be a VM, or something completely different.

I'd like to avoid having downstream logic here, that adds cyclic coupling.
Why not either do:
* a minimal overwrite in PVE, would have the additional benefit of not needing
  to touch all use sites there.
* replace the "type" property with a "task" property, avoiding the need to map.

If we touch this we could also make this more explicit with a default off "purgeable"
(or similar name) config property.
