Description of problem:

While following https://access.redhat.com/documentation/en-us/red_hat_satellite/6.14/html-single/provisioning_hosts/index#Using_an_Image_Builder_Image_for_Provisioning_provisioning , After submitting the host for build with kickstart_liveimg parameter, The process is unable to fetch kickstart or render\preview the Kickstart template shipped with Red Hat Satellite 6.

Version-Release number of selected component (if applicable):

Satellite 6.14 [ perhaps some older versions are affected as well ]

How reproducible:

Always

Steps to Reproduce:
1. Create a system with kickstart_liveimg parameter added
2. Try to render\preview the kickstart template against that host
3. Repeat Step 2 with both Safemode Rendering enabled and disabled

Actual results:

With Safemode enabled:

It seems foreman does not even know where the repository_url function exists or what to pick from.

Expected results:

No such error and end-users would be able to deploy systems using the RH Image builder images and the documented procedure in "Chapter 8. Using a Red Hat Image Builder Image for Provisioning"
