This patch fixes:
- invalid client package name for RH platform
- missing common package installation in init.pp
- package/group/directory creation order for CentOS,
but leaves invalid order for Ubuntu because without
it is not installable (see bug #1365561)
- exists_notification_transformer is disabled
to workaround bug #1402055
