RDO is currently working on python3 support for the next version of
CentOS/RHEL based systems. This package uses the distro_python3 flag
that was added as part of I4028991bad92c0e8e21066cc4173c06ce5eba393 to
use the python3 specific package names. This change only adds python3
package names for RHEL systems.
