Introduce rhsm_release parameter

So we can configure a specific release when subscribing the node.

It has been reported on https://bugzilla.redhat.com/show_bug.cgi?id=1839063
that setting a release was required to get rpms from
rhel-8-for-x86_64-baseos-eus-rpms repository when installing OpenStack
on RHEL8.
