Description of problem:
When dnf repositories are enabled on the installed system, initial-setup becomes unresponsive for a while after clicking the "Finish configuration" button.
journalctl shows that repository metadata are being downloaded during this freeze and only after that initial-setup is closed and the system continues:

...

This only happens when subscription-manager-initial-setup-addon is installed. If the package is uninstalled, metadata are not downloaded and there is no significant delay before clicking the "Finish configuration" button and closing initial-setup.

To reproduce this issue it's good to have repositories with big repodata and/or using slow network connection.

Version-Release number of selected component (if applicable):
RHEL-8.6, RHEL-8.7
initial-setup-0.3.81.7-1.el8
subscription-manager-initial-setup-addon-1.28.32-1.el8

How reproducible:
Always

Steps to Reproduce:
1. Install RHEL-8 with the default package set (Server with GUI) and register to CDN during the installation.
2. Reboot to the installed system.
3. Accept the EULA in initial-setup and click the "Finish configuration" button quickly.
4. An alternative approach is to configure dnf repositories on the installed system, run "dnf clean all && systemctl enable initial-setup" and reboot the system.

Actual results:
initial-setup freezes until metadata are downloaded.

Expected results:
initial-setup finishes without a significant delay, or there is a notification that metadata are being downloaded.
