rhel subscription PR forces ~/rhn_username to exist

[cgwalters]

#16 breaks k-a for me in that now all of my hosts need to have two file named ~/rhn_username and ~/rhn_password even if I'm already subscribed, because the variables are evaluated before Ansible has a chance to determine I'm already subscribed.

I'm feeling that the problem of subscribing the host is not something k-a should attempt to address itself - we suggest you ensure the machines are set up beforehand for this.

@cgwalters Sorry for breaking you. :(

It's a valid point. Subscribing is typically a ks/cloud-init task that's part of basic bootstrapping.
