Fix DNS plugin: proper output definitions, --all, dns-add-rr overwritting

The DNS plugin is getting old, tired and already looking forward to his
pension in the Carribean. It will be replaced soon by a younger, faster,
safer, shorter (in terms of code) and more maintainable version.
Until that happens, here's some medicine for the old guy:
- proper output definitions: the DNS plugin was created before we
  had the has_output attribute in place
- --all: this is related to the output definitions as
  Command.get_options() adds the --all and --raw options automatically
  if has_output contains entries
- dns-add-rr overwritting: missing .lower() caused records to be
  overwritten everytime a new one was added from the CLI
