Distro packaging includes a lot of configuration files that this module tries
and fails to get rid of, but with exclusions. Those don't always work for
mysterious reasons. Leave the distributed files intact as much as possible,
with just the necessary files touched to effect the desired configuration.
Also, make inclusion of named.conf.local optional (default false) and stop
ensuring that there's at least an empty one.
`dnssec-keygen` uses `/dev/random` by default, but this is slow in some
scenarios where `/dev/urandom` is both faster and provides sufficient utility.
Allow override via the `bind::random_device` hiera key.
Previous iterations and even a release were all broken. The module works again,
sorry for the interlude.
- Giving up on params and moving to module_data (WIP)
- Change the Package and Service references to the static 'bind' name
- Add a meager amount of test coverage
