generated client cant stream responses

まだ誰も着手していません。

# can we have the ability to getReader instead?
```ts
const logs = await docker.containers.containerLogs(id, {
follow: true,
stdout: true,
});
```
will never resolve because 'follow' is true.

Start at the generated containerLogs entry point and trace how the response is handled when follow is true. Reproduce the unresolved promise with the example request, then determine how the client should expose a readable stream or reader and verify that the request can consume ongoing logs without waiting for completion.
