Add NS Pools Config and RNDC key

Will create a example Pools config that is used by Designate service to target a Bind9 Nameserver. This can change if using for example PowerDNS

Openstack Designate Pools Documentation Link

Add designate pools file

vim /etc/genestack/helm-configs/designate/designate-pools-helm-overrides.yaml

Example designate-pools-helm-overrides.yaml

conf:
  pools: |

      # The name is immutable. There will be no option to change the name after
      # creation and the only way will to change it will be to delete it
      # (and all zones associated with it) and recreate it.
