Cloned from https://bugzilla.redhat.com/show_bug.cgi?id=1398945

Description of problem:
User scenario: I want to enable some CDN repo. Going to WebUI -> Content -> Red Hat Repositories. Once that is loaded, navigating / unwrapping any "tree leaf" (that already shows particular repos, not sub-tree), this step takes tens of seconds.

The reason is evident when enabling debug logs:

Rails.logger.debug "CDN: Requesting path #{used_url}" in /opt/theforeman/tfm/root/usr/share/gems/gems/katello-3.0.0.82/app/lib/katello/resources/cdn.rb is logged for each and every path that katello scans on CDN. Unwrapping " Red Hat Enterprise Linux 6 Server (RPMs) " logs
