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
The idnsUpdatePolicy takes a list of BIND dynamic update policies, each
of which must be terminated by ";". Also fix a minor error in the
documentation string.
