Add network elements as a dict in Kubernetes context

Like in Heat context, network elements should be defined in a
dictionary, using the network name as the entry key.

Previous implementation:
  context:
    networks:
      - name: ...
        plugin: ...
        args: ...

New implementation:
  context:
    networks:
      net_name_1:
        plugin: ...
        args: ...
      net_name_2: ...
