Additional RHEL fixes:
- Don't remove subscription-manager because baseos is subscription managed.
- Disable any remaining subscription managed repos that are replaced by
RockyLinux repos.
- Hide digest messages from rpm.
Various fixes to allow RHEL conversions to work:
- adding additional commands to bin_check
- Fixed awk command to parse out the gpgkey for a repo.
- provides_pkg() which returns a package name for a given provides.
- allow additional packages to be removed without replacing them with rocky
equivalents.
- Don't bother checkign the exit status of dnf shell, it doesn't return a valid
fail status anyways.
- Instead check to make sure that the appropriate packages have been removed and
installed. If not attempt to fix with rpm.
