Fix regression in url encoded salt-api messages

Most clients that do url encoding include other data in the Content-Type field (requests for example sets "application/x-www-form-urlencoded; charset=utf-8"). This changes the api to be a more forgiving server which will make any non-list struct a list

Revert commit 1a90b5f.
Adds a function to store/update dns serial numbers

avoid manually updating the serial number of a
zone file each time the zone file changes.

Example use:

/etc/bind/example.com.zone.include:
  file.managed:
    - source: salt://dns/example.com.zone.include
    - template: jinja
    - user: root
    - group: root
    - mode: 644
    - require:
      - pkg: bind9
    - watch_in:
      - service: bind9

/etc/bind/example.com.zone:
  module.wait:
    - name: dnsutils.serial
    - update: True
    - zone: examplecom
    - watch:
      - file: /etc/bind/example.com.zone.include
  file.managed:
    - source: salt://dns/example.com.zone
    - template: jinja
    - require:
      - module: /etc/bind/example.com.zone

The include file contains all the dynamically generated zone data, the
example.com zone files is mostly static and has a serial number like:

{{ salt['dnsutils.serial']('examplecom') }}      ; serial number YYMMDDNN
