The designate-operator will need to configure the unbound stub zones if they are provided by the deployer.

This is one of three BZs covering configuring unbound.

"stub-zone:" section (recommend /etc/unbound/conf.d/designate-stubs.conf?)

If the deployer sets a list of TLDs that they plan to delegate to Designate, we can setup stub-zones for those that point to the Designate BIND instances. This reduces load on the customers resolvers and improves the performance for looking names up for these zones.

Note: The list of TLDs provided in the new tripleo setting described below should also be automatically added to Designate via the API if they do not already exist.

Note: We will need to know the list of Designate BIND IPs before creating this file.

For each TLD (optionally) provided by the customer: <<<< This will be a new tripleo configuration option for deployers.

stub-zone:
name: "<the TLD such as mycloud.redhat.com>"
stub-addr: <Designate BIND IP addr>
stub-addr: <Designate BIND IP addr2> (i.e. one per BIND instance in cloud)
stub-prime: yes
stub-first: yes
