Greg Shikhman 1ba739a6b6 Refactor DnsWriter into the model package
This is one of several CLs in order to support per-TLD DnsWriter
implementations, modeled on the work done for PremiumPricingEngine.

Since DnsWriters will be set inside the Registry object, the DnsWriter
interface definition needs to be moved to models to create minimal
dependency on the rest of the registry codebase to avoid cyclic
dependency.
