Creates a new object for connecting to the DNS service.
 Each call creates a new connection.

 @param [String, Array<String>] scope The OAuth 2.0 scopes controlling the
   set of resources and operations that the connection can access. See
   [Using OAuth 2.0 to Access Google
   APIs](https://developers.google.com/identity/protocols/OAuth2).

   The default scope is:

   * `https://www.googleapis.com/auth/ndev.clouddns.readwrite`
 @param [Integer] retries Number of times to retry requests on server
   error. The default value is `3`. Optional.
 @param [Integer] timeout Default timeout to use in requests. Optional.

 @return [Google::Cloud::Dns::Project]

 @example
   require "google/cloud"

   gcloud = Google::Cloud.new
   dns = gcloud.dns
   zone = dns.zone "example-com"
   zone.records.each do |record|
     puts record.name
   end

 @example The default scope can be overridden with the `scope` option:
   require "google/cloud"

   gcloud  = Google::Cloud.new
   dns_readonly = "https://www.googleapis.com/auth/ndev.clouddns.readonly"
   dns = gcloud.dns scope: dns_readonly
