Hack to take advantage of the code-generated serialization code.
Initializing/destroying ApiClient objects is surprisingly expensive
(because it involves a threadpool), so we allow passing an existing
instance. If you already have a full-on API connection `api`, you can
access the ApiClient object as `api.api_client`. This is such a speed-up
that this argument may become mandatory.
