Error setting host relationship in "long" format

[Miguel Caballer]

If you set the host requirement in long format (setting the capability type and/or the relatinship type) and the function get_property or get_attribute are used the parser fails:

node_types:

  tosca.nodes.SomeSoftwareComponent:
    derived_from: tosca.nodes.SoftwareComponent
    properties:
      test:
        type: string

topology_template:

  node_templates:

    some:
      type: tosca.nodes.SomeSoftwareComponent
      properties:
        test: { get_attribute: [ HOST, private_address ] }
      requirements:
      - host:
          node: server
          capability: tosca.capabilities.Container
          relationship: tosca.relationships.HostedOn

    server:
      type: tosca.nodes.Compute

This is the error:

[OpenStack Infra (hudson-openstack)]

This issue was fixed in the openstack/tosca-parser 1.3.0 release.

Nice. Thanks Miguel!
