While it is entirely possible that the feature is broken, it seems that in
this case you're expecting the allowed_address_pairs to populate fixed_ips.
Neutron does many crazy and unreasonable things but asking you to pass an
attribute in the request to populate another attribute is not one of these!

Basically allowed address pairs are MAC/IP pairs for which you allow
traffic on a port, but that are not managed by neutron. This means that, in
your case, if you defined an additional IP address and set it to 192.168.0.58
in your instance, Neutron would allow traffic from or to that address. If
you did not explicitly add that address in allowed_address_pairs neutron
would block traffic to and from it.
>From the CLI, you should be able to see allowed address pairs configured on
a port with neutron port-show

If you wanted to configure 192.168.0.58 as your port's IP address and let
neutron manage it, you should be able to use the fixed_ips
attribute, although I don't know how to leverage that through Heat
templates.
