named-checkconf option to include defaults in output
A customer has requested an option for
named-checkconf to integrate the full set of defaults into the output.
One of the purpose of this is to make it easier to document (e.g. for an external operations team) all of the configuration options values that are being used by BIND without having to consult the ARM (and make sure that you're looking at the version of the ARM that matches the version of BIND that you're running).
