One-network deployment is impossible

[Sergey Vasilenko]

Deployment without dedicated management network is impossible, because in some manifests used deprecated hiera('nodes')
instead network_metadata section.

In One-network case we have no IP addresses into nodes:

---
nodes:
- fqdn: node-4.domain.local
  name: node-4
  role: primary-controller
  swift_zone: '4'
  uid: '4'
  user_node_name: CNT21
- fqdn: node-5.domain.local
  name: node-5
  role: compute
  swift_zone: '5'
  uid: '5'
  user_node_name: CO22
- fqdn: node-6.domain.local
  name: node-6
  role: compute
  swift_zone: '6'
  uid: '6'
  user_node_name: CO23

Solution: to use network_metadata as source

Second part of problem. On compute node for network scheme, like:

    network_scheme:
      transformations:
      - action: add-br
        name: br-fw-admin
      - action: add-port
        bridge: br-fw-admin
        name: eth0
      endpoints:
        br-fw-admin:
          IP:
          - 10.88.0.6/24
          gateway: 10.88.0.2
      version: '1.1'
      provider: lnx

function configure_default_route() has no ability for setup true route, because route through admin network already exists.

    Use network_metadata hash instead of deprecated nodes list

    for generate /etc/hosts file

    Deployment with network template: One-network deployment is impossible

    Deploy cluster with specific network configuration:
     No dedicated management nework.

    This is automated test for already fixed and manually tested bug.
