ironic: Remove tasks for image migration

This removes the tasks to copy image data from /(http|tftp)root to
/var/lib/ironic/(http|tftp)root. These tasks were implemented to
migrate image data from the old paths we used before containerizing
undercloud and now all image files should be created in the new paths
by the overcloud image command.
