Fix in libtaskotron: https://pagure.io/taskotron/libtaskotron/c/976df06e1ee5f7f8b9a97d163fb8f4fe32bde44a?branch=develop

base_images change: https://pagure.io/taskotron/base_images/c/1e11d57d50406bffd764d5bae4eb741bf7f015bb?branch=master

Not deployed yet.

base_images change deployed, ran playbooks (dev, stg, prod) to reconfigure imagefactory to also build f30 and f31 images.

@kparal pushed new libtaskotron to updates, once landed, we can close this.

Production instance will be update later when we move it from Fedora 27.
