Disabling container validation when running redhat-subscription

subscription-manager will fail if run from within a container. Since
some nodes are bindmounting /run, a .containerenv file is exposed
inside /run on the hosts and this breaks subscription-manager on
overcloud nodes.

We can bypass this validation from subscription-manager by enabling the
SMDEV_CONTAINER_OFF environment boolean as described here [1].
