Add useful fields for Authoritative Zone resource

[bsmithtm]

Context

When creating an Authoritative Zone in DNS using the current client, only the desired FQDN is accepted as an argument. This does not allow a user to set a Nameserver Group, or the TTLs for SOA records, for instance.

CreateZoneAuth(fqdn string, ea EA) (*ZoneAuth, error)

Proposed Changes

Add the following fields for Authoritative Zone resources. These are already present in the Infoblox NIOS API, they just aren't exposed here in the Go Client.

• ns_group
• restart_if_needed
• comment
• soa_default_ttl
• soa_expire
• soa_negative_ttl
• soa_refresh
• soa_retry

Related Work

With these fields exposed in the Infoblox Go Client, we can then add an Authoritative Zone resource to the Infoblox Terraform Provider.
