split config files in directory

[ybrock]

It would be very convenient to be able to split zone config files separatelly, which makes everything easier to maintain and read.
Having all zones defined in /etc/named/[zone].conf, loaded by /etc/named.conf would be very usefull.

I've tried declaring many instances of bind::server::conf {'/etc/named/.zonea.conf' ....
but this approach is not working, as every zone inherits the whole /etc/named.conf parameters and Bind complains (options, acls, ... are redeclared in every file).
It would n't be that complicated to add a parameter "split_zone_config" and use another template for this.
