Description of problem:

A RHEL8 system is registered to a Satellite server that has Simple Content Access enabled. The RHEL8 content host has custom repositories disabled via the repository sets. Yet, a RHEL8 container running on this content host does not honor the disabled repository sets, and instead the custom repositories are showing as enabled.

Further, the /run/secrets/redhat.repo file on the container matches the /etc/yum.repos.d/redhat.repo file of the host exactly (all the custom repositories are disabled). But the /etc/yum.repos.d/redhat.repo file on the container has the custom repositories enabled.

When Simple Content Access is disabled, the RHEL8 container honors the same repository set for custom repositories as the RHEL8 content host it is running on. That is, when the content host has the custom repositories disabled via repository sets from Satellite, the RHEL8 container also has these custom repositories disabled.

Version-Release number of selected component (if applicable):
Satellite 6.13

How reproducible:
always

Steps to Reproduce:
1. Satellite with SCA enabled.
2. Create custom repositories.
3. Disable custom repositories for a RHEL8 content host via repository sets.
4. Create a RHEL8 container on the content host, run the "exec" docker/podman command with interactive shell and observe that "yum repolist" shows the custom repositories are enabled.

Actual results:
RHEL8 container has custom repositories enabled.

Expected results:
RHEL8 container should match the host it is running on, and custom repositories should be disabled if the repository set of the content host has the custom repositories disabled.

Additional info:
