Set Response Body and Status Code

[qoomon]

Feature Request

Is your feature request related to a problem? Please describe.
I'd like to manually set the Response Body and Status Code e.g.

app.on("workflow_job.queued", async (context) => {
       context.res.status(400);
       context.res.send('None shall pass');
});

Currently the response code is always 200 even if an error got thrown. e.g.

app.on("workflow_job.queued", async (context) => {
       throw new Error('Boom');
});
