WHT-31 

Pull request for review from @elmariofredo 
This should be targeting main frontline node within the cluster so we want to `fl.{{ salt['grains.get']('circle') }}.ourdomain.com` instead, what you can do is to specify something like app.domain in pillar file and make it this way `fl.{{ salt['grains.get']('circle') }}.{{ pillar['app']['domain'] }}`
