RedHat's default zones are baked into the stock named.conf, which the module's
template completely rewrites. Since the module is extremely view-based, and the
Debian default-zones are repositioned into the zones, let's take those defaults
out of the stock named.conf, build a configuration file out of them and include
it in the view just the same.
Modify the handling of the `servers` property in `bind::view` to respond to
specific keys in the config hash for each server, and document how this
property is handled.
Make recursion_match_clients and recursion_match_destinations mirroring the
existing match_clients and match_destinations in order to distinguish recursion
access as a proper subset of view access.
Unless specified, this defaults to "localnets, localhost only" yet the
intention of specifying a match-clients and recursion is to allow recursive
queries from the given address not just localnets. This change adds the
specified match-clients under allow-recursion.
If match-destination is specified instead, then allow-recusion-on is
set for those interfaces.
