Default Backend Server

This is a simple webserver that satisfies the ingress, which means it has to do two things:

Serves a 404 page at /
Serves 200 on a /healthz

Server respond JSON instead of plain text

Not found page:

$ curl http://localhost:8080
{"code":404,"message":"Not found"}

Status page:

$ curl http://localhost:8080/healthz
{"status":"ok"}

Why?!

In my projects, it's important that alive server respond JSON, even if this is default backend server. This image is only 2mb which is extreamly small compare to others custom error images.

Also I personally think JSON response looks better than html error without formatting
