As a result of RHELDST-19794 and RHELDST-22443, we can start using convert2rhel repofiles located at https://cdn-public.redhat.com/. The repofiles point to convert2rhel repositories that located at https://cdn-public.redhat.com/ as well.

Advantages:

• We don't need to take care of installing the Red Hat self-signed SSL certificate /etc/rhsm/ca/redhat-uep.pem necessary for accessing https://cdn.redhat.com/ which we've used to access convert2rhel repositories. The new location https://cdn-public.redhat.com/ uses an SSL cert signed by a trusted Certification Authority.
• Having both the repofiles and the repositories on one domain looks more trustworthy and professional. Besides that, the ftp.redhat.com is hosted on a single AWS VM and the CDN is definitely more reliable.

Acceptance criteria:

• In the code including tests, we:
  • get rid of handling the redhat-uep.pem cert
  • use the new repofile URLs on the public CDN:

    https://cdn-public.redhat.com/content/public/addon/dist/convert2rhel/server/7/7Server/x86_64/files/repofile.repo 

    https://cdn-public.redhat.com/content/public/addon/dist/convert2rhel8/8/x86_64/files/repofile.repo

• • use the new repo URLS on the public CDN:

    https://cdn-public.redhat.com/content/public/addon/dist/convert2rhel/server/7/7Server/x86_64/os/ 

    https://cdn-public.redhat.com/content/public/addon/dist/convert2rhel8/8/x86_64/os/
