Rename list_subid_ranges to getsubids to provide a system binary to check the sub*ids of a user. The intention is to provide this binary with any distribution that includes the subid feature, so that system administrators can check the subid ranges of a given user. Finally, add a man page to explain the behaviour of getsubids. Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1980780 Signed-off-by: Iker Pedrosa <ipedrosa@redhat.com>
