Unify logging

[Esemesek]

Unify logging through-out the cli. We will need a couple of levels of logging:

• ERROR
• WARNING
• INFO
• DEBUG - we will need it for --verbose logging

Could be very similar to Haul's logger: https://github.com/callstack/haul/blob/next/src/logger.js

[Esemesek]

I've added simple logger (cli/src/util/logger) to the project. It should be okay for now. We still need to replace all the console.log, console.warn, console.error and npmlog:

• - cli/src/* (taken)
• - cli/src/bundle
• - cli/src/core
• - cli/src/dependencies - We are dropping this, so no need to add custom logging here
• - cli/src/eject
• - cli/src/generator
• - cli/src/info (taken)
• - cli/src/init (taken)
• - cli/src/install (taken)
• - cli/src/library (taken)
• - cli/src/link
• - cli/src/logAndroid
• - cli/src/logIOS
• - cli/src/runAndroid
• - cli/src/runIOS
• - cli/src/server
• - cli/src/util

If anyone is interested in grabbing something just write it here.

@Esemesek I want to help on this one. Should I do it in a fork or wait to be assigned?

[Esemesek]

@sidferreira just tell me what part can you take, and I'll assign it to you C:

[sidferreira]

@Esemesek is there a base branch for it? I may be wrong but it sounds like a quick task if done with regular expressions...

[thymikee]

There's no branch, we just file small PRs to not disrupt others work too much :) Since there's not much left, feel free to send a PR with all of it 👍

[sidferreira]

@thymikee Just to be sure: only on packages/cli/src right?

[thymikee]

Yup!

[sidferreira]

@thymikee @Esemesek seem that npmlog isn't in use anymore

[thymikee]

Oh, that's cool! But there should be some regular console.logs that would be nice to convert to universal logger

[sidferreira]

@thymikee yeah, I replaced any console.something

[sidferreira]

@thymikee close?

[thymikee]

Awesome work @sidferreira, thank you so much!
