Does not work out of the box

Including powerdns in the top.sls and running highstate results in it failing to render the configuration:

You have to set "dns-supermaster" in minion's grains, like this:

grains: role:

• dns-supermaster

You also have to define a "networks:dns-master:ip" resembling the dns master ip address.

The formula works in the following scenario: -1 hidden master (dns-supermaster) -1 master (dns-master running bind)

• as many slaves as you want running bind

To formula definitely needs some love and made to be more generic, not so specific.

@costibleotu It would definitely be much appreciated if you could work on making it more generic and ensure that the formula can be used as-is.
