Refactor formula to match template-formula

[alxwr]

• use defaults.yaml & Co.
• reduce Pillar data
  i.e. this needs to go:

dnsmasq:
  dnsmasq_conf: salt://dnsmasq/files/dnsmasq.conf
  dnsmasq_hosts: salt://dnsmasq/files/dnsmasq.hosts
  dnsmasq_cnames: salt://dnsmasq/files/dnsmasq.cnames
  dnsmasq_conf_dir: salt://dnsmasq/files/dnsmasq.d

@myii @aboe76 Please add suggestions if you have any.

@alxwr Thanks for this. A few more, some stating the obvious:

• Update map.jinja.
• Change {%- ... -%} => {%- ... %} (ref).
• Use TOFS for all file handling.

I agree that this formula needs some work, @alxwr quotes some pillar which appears useless to me too
