From the parent epic https://issues.redhat.com/browse/SAT-30605:

• Any existing procedure that is missing a reference to a related REX template that is worth highlighting
  • See https://docs.theforeman.org/nightly/Upgrading_Project/index-katello.html#upgrading_smart-proxy_server_upgrading-connected – the NOTE that mentions a REX template related to the procedure

The goal is to identify existing procedures in the docs set that could benefit from a reference to a REX job template that is designed to perform that action.

The goal is not to add this reference to all procedures. There are over 100 job templates and we shouldn't try to reference them all from all procedures, only from the high-impact ones.
