Zone record json struct tag inconsistent casing

[Ivan-Z]

For the domain property on the zone record struct, why is the JSON tag capitalized? https://github.com/ns1/ns1-go/blob/v2/rest/model/dns/zone.go#L59 It is inconsistent with the rest of the code base, and breaks some code-gen tools when trying to integrate with the ns1-go package.

@Ivan-Z Thank you for reporting this issue. We already added this to our backlog.

Hi Ivan, it's definitely inconsistent and not ideal, but changing it might cause trouble for anyone with code that uses marshal/unmarshal on that struct.

Can you give us more details on the code-gen tools that were having trouble integrating with ns1-go? Were you able to find workarounds?

This fix will go out with the next version bump
