Various RHEL fixes
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.
