When the ip_address property of a tosca.nodes.network.Port object is specified heat-translator fails with an error from tosca_network_port.py:

Traceback (most recent call last):

    fixed_ip['ip_address'] = value
TypeError: list indices must be integers, not str

The problem is that tosca_network_port.py declares fixed_ips = [] instead of fixed_ips = {}, and then it uses it as a dict.
