Add list of required SUSE content for host registration

[maximiliankolb]

What changes are you introducing?

Add table to help users with registering SLES hosts to Foreman+Katello

Why are you introducing these changes? (Explanation, links to references, issues, etc.)

current table in downstream only contains the repositories but not the way to get there content > products > a product > a repository.

Anything else to add? (Considerations, potential downsides, alternative solutions you have explored, etc.)

table is already part of orcharhino downstream docs; it's only added the products that contain the required repositories

• https://docs.orcharhino.com/or/docs/sources/guides/suse_linux_enterprise_server/managing_hosts/registering_hosts.html#Registering_Hosts_Using_the_Bootstrap_Script
• https://www.suse.com/lifecycle#suse-linux-enterprise-server-15

no diff is to be expected because the snippet is only included for SLES. If you have an idea on how to provide this to upstream Katello users, please let me know.

Example on Foreman+Katello with foreman_scc_manager (requires a valid SCC account):

users have to select products and sub-products in the SCC Manager plugin; and then, during host registration, insert the "Published At" URL. They need a mapping from "product name in katello > repo name in Katello" to simplify this. I can show this in a 1:1 meeting if anyone wants to have a peek at the SCC Manager plugin together.
