Prepare for dnsx.Manager to operate on zones

[stephen-soltesz]

This change includes two updates:

• Adds a new package dnsname that now includes OrgZone and two new functions for ProjectZone and OrgDNS, both of which will be needed to generate the project and org zone names.
• Extends the dnsiface.Service interface to includes methods to GetManagedZone and CreateManagedZone.
• Adds dnsiface.NewCloudDNSService for consistency with other interface types
