Filtering of port list by fixed-ip doesn't work

[Dr. Jens Harbott]

The recently added option to filter the port list output does not work for me. The following commands all produce identical output, even when there are ports with different addresses and subnets:

- openstack port list
- openstack port list --fixed-ip subnet=<valid subnet id>
- openstack port list --fixed-ip ip-address=<any ip>
- openstack port list --fixed-ip subnet=<valid subnet id>,ip-address=<any ip>

I do get an error when I specify a non-existing subnet id.

openstack --version: openstack 3.12.0
The cloud I am testing against is based on Ocata.

So it seems like the patch introduced in https://review.openstack.org/388575 is incomplete, it needs a matching patch in openstacksdk in order to allow filtering by fixed_ips there.

Also the tests in that patch are bogus, they in fact verify exactly the behaviour described above.

With that patch in openstacksdk, filtering is working as expected for me, but I fear that it will break unit tests for osc because they are confirming the non-filtered scenario.

    Allow filtering network ports by fixed_ips

    The patch in [1] introduced filtering network ports by fixed-ip in the
    openstackclient, but it doesn't really work because the filter isn't
    accepted in the sdk.

    Add that option and add an unit test for the filter list.
