Pretty logs, address option, update notifier

[delvedor]

This pr is to prepare the direct integration of the cli with Fastify, once we approve this I'll update Fastify by adding the following code to the package.json:

  "bin": {
    "fastify": "./node_modules/.bin/fastify"
  },

In this way the users can use the cli out of the box.

What is inside this pr:

• Added pretty logs with pino-colada
• Added address option
• Added update notifier for fastify

LGTM, but I do not think your bin section will work when installed both when installed with -g and with --save. npm layout is not-deterministic, so you'll need to do require('fastify-cli')() or something similar.

Yeah, you are right.
If we install fastify-cli as dependency in Fastify and we add it in bin will work only if the user runs it via npm.

npm layout is not-deterministic, so you'll need to do require('fastify-cli')() or something similar.

I didn't understand this.
