Katello+RedHat Repositories

Hello Guys,

i was wondering, is it possible to use RedHat repositories with CentOS

Now we are using this project
https://github.com/brdude/pulp_centos_errata_import to provide new
Errata-Updates to CentOS-Systems.

We have an RedHat-Subscripton "Red Hat Enterprise Linux Desktop,
Self-support <https://access.redhat.com/management/subscriptions/3904615>"
but i have no idea if this subscription is enough to get Errata-Updates
from RedHat.

On Katello site is only a quick how-to, but the is no explanation what
subscription-type we need to be able to create a manifest file to import
into Katello.
