Centos7-katello-devel-stable won't work with centos7-proxy-devel box

[johnpmitsch]

When spinning up an external foreman proxy, it takes a "server" variable and that is a short hostname which appends on your hypervisor domain namespace.

The stable katello box is pre-installed with katello and then published as a vagrant box. So the hostname is already set and does not use any information from the forklift user's hypervisor. This means that the server hostname on the foreman-proxy box is not set correctly with the stable box.

As an example, the foreman proxy looks for centos7-katello-devel-stable.jomitsch.example.com instead of the actual stable box's hostname centos7-katello-devel-stable.example.com when you specify server: centos7-katello-devel-stable in the ansible variables for the proxy box.

This means that communication between the external foreman-proxy and the stable katello box can not happen at spin-up time

A potential workaround is update /etc/hosts with centos7-katello-devel-stable.example.com, though I haven't tried it personally.
