With `openstacksdk` 3.2.0 the `host` attribute of an Instance got added
to the `Server` class [0]. With that change, listing servers with the `host`
attribute leads to a query-filter for `compute_host` as expected, but
`openstacksdk` will also filter for the `host` attribute locally after
the results are returned. Since `compute_host` being
`OS-EXT-SRV-ATTR:host` is not the same as `host, this means no results
are returned.
Since we want to keep the old behaviour of filtering by `compute_host`
i.e. the service host name, we need to switch to filter for
`compute_host`. This is already supported in older versions of
`openstacksdk`.
