"openstack port list --security-group <id>" was using a filter that
didn't exist in `openstacksdk`: "security_groups". Up until version
1.0.1, `openstacksdk` did not support filtering `Port` objects by
security groups. Later versions will support the filtering (via [1]),
but the filter is called the same way the attribute on the `Port` object
is called: `security_group_ids`.
We're not bumping the `openstacksdk` version here, because the feature
we're using [1] is merged too recently and a bump of min requirements
thus unlikely. `openstackclient` continue to work with older versions of
`openstacksdk` - the "--security-group" filter will just do nothing like
before.
