Remove the node.js development server

[stewartfrancis]

Remove the node.js development server used for testing the z/OS connect APIs in designer, and replace with nginx, so we don't have to maintain a separate server

Thanks Stew, testing now but looks good! Will merge shortly

@stewartfrancis when running it locally, the frontend was still requesting http://localhost:3001/api/customers/1234, we actually want to request http://localhost:9080/customers/1234 (no /api).

I don't know if the location block in nginx is supposed to resolve this?

Bob advised this instead which worked when running locally, but I don't know if you had wider reasons for your nginx conf

    # Proxy API requests to the backend zosConnect service
    # Frontend makes requests to /api/* which nginx forwards to zosConnect:9080/*
    location /api/ {
        proxy_pass http://zosConnect:9080/;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }
