when 'import-from' contains a disk image that needs extraction
(currently only from an 'ova' archive), do that in 'create_disks'
and overwrite the '$source' volid.
Collect the names into a 'delete_sources' list, that we use later
to clean it up again (either when we're finished with importing or in an
error case).

changes from v1:
* put extraction into branch for managed volids
* adapt to new module location
* add checks for the impor storage if it support 'images'
(otherwise we cannot extract there)
* add cleanup to other 'create_disks' method
