Property error: resources.VipPort.properties.fixed_ips: "{}" is not a list

[Dan Prince]

Seeing the following failures when trying to use the latest Heat code I'm seeing the following (new) failures with tripleo-heat-templates:

The nested stack for the VipPort has a default set to [] which should take effect but it isn't working anymore.

This is a side-effect of this merge[1] that happened few days back. I'll push a patch soon.

    Fix "{}" is not a list error for json parameter type

    If json paramter `default` of nested stack is set to
    [], it resets it to {} and nested resource validations
    fail. This patch fixes it by allowing empty list to
    passthrough.
