custom renderer option added to cli

[muslumozturk61]

In my reactjs app, I need to wrapped mock api response. So I added this feature to json-server.

This is my sample renderer.js file code:

module.exports = (req, res) => {
res.jsonp({
version: "v1",
statusCode: 200,
isError: false,
message: "The Request successful.",
result: res.locals.data,
})
}

The sample usage is :

json-server db.json --custom-renderer ./renderer.js
