* buildinstall
* createiso
* image_build
* live_images
* product_img

CHANGE: createrepo_c is config option now defaults to True.
ACTION: You can safely remove 'createrepo_c = True' from config files.
Set 'createrepo_c = False' if you need legacy createrepo.

ACTION: Add 'createrepo_checksum = "sha256"' (or "sha") to config files.
