Any RHEL 8.4+ AMIs launched in cloud, would have auto_registration enabled and hence, as they are not expected to consume content directly from redhat cdn or a satellite\katello\foreman, The manage_repos option is by default set to 0 or disabled.

In order to register such a system back with a satellite\foreman\katello instance, it's important that we force manage_repos to be enabled ( set to 1 ) so that, after the registration the systems can see and consume repos from the parent satellite\katello\foreman instance and complete the post-registration steps as well.

Steps to reproduce:

• Take any RHEL 8.10 or 9.6 system

• Run this command on the same system i.e.
  • subscription-manager config --rhsm.manage_repos=0 
  • subscription-manager refresh
  • yum clean all

• Then try to register the system with the satellite server using the global registration command.  

Actual Results:

The system is registered but have access to no repositories. Sometimes that causes the whole registration process fail to complete as well.

Check the output of "subscription-manager config" command and manage_repos is set to 0. 

Expected Results: 

Before the actual registration is done, the manage_repos should be set to 1. The same request was done back in 6.9 but were not implemented.
