[openbook] missing node name on vip

[Michał Górniak]

on fuel 8 plugin we have network_roles.yaml with definition:

- id: "openbook"
  # Role mapping to network
  default_mapping: "management"
  properties:
    # Should be true if network role requires subnet being set
    subnet: true
    # Should be true if network role requires gateway being set
    gateway: true
    vip:
       - name: "openbook_public"
         namespace: "haproxy"
         #node_roles: ["openbook"]
         alias: "openbook_public"

if node_roles is empty fuel will fill up this with default values:

openbook_public:
    network_role: openbook
    vendor_specific:
    namespace: haproxy
    ipaddr: <IP>
    node_roles:
    - controller
    - primary-controller

and this will fail puppet manifest on primary-controller during redeploy, it should be changed or removed because i see no reason to use VIP with only one node for openbook.
