RequestHandler should be able to pass additional details in the response body

As I plugin author, I should be able to pass any data in the response body

kibana/src/core/server/status/routes/status.ts

Line 164 in 987c736

return res.custom({ body, statusCode, bypassErrorFormat: true });

The only way to pass error details in the response body is via the attributes property. It works in a hapi-compatible manner and stores a passed object under attributes property in the response body. For cases when a plugin needs to pass additional data in the response body, we have to use a workaround.

In retrospect, the bypassErrorFormat workaround that was implemented was probably good enough, I don't think we'll need to make it a more fully fledged API, so I'll go ahead and close this.
