Use winston instead of npmlog

[pragmaticivan]

npmlog concerns:

• we need to pass a false boolean for most of the logs ex: log.info(false, 'Starting plugins…');
• There's no support for different transports ex: https://www.loggly.com/docs/node-js-logs/

We were using wiston in the beginning and even looking to both projects GitHub, it's clear that Winston has more updates/maintainability

winston is a nice project, although it's considerably more bloated than npmlog, do we have enough logging requirements to worth the change?

Another alternative suggested by @cirocosta seems to be really good https://www.npmjs.com/package/pino it also has a middleware for express.
