Use mozlog logging format to get access to server logs

[jasonthomas]

https://wiki.mozilla.org/Firefox/Services/Logging contains a description about the mozlog format. Switching to mozlog will help get addons-frontend hooked up to Logging 2.0 https://mana.mozilla.org/wiki/display/SVCOPS/Logging+2.0

Seems doable. We use bunyan (which already supports JSON) so maybe we can hook it up to mozlog.

This is high-ish priority. I'm putting it in the London Work Week milestone but anyone should feel free to grab it before then.

We need to do this if we want to see logs in the [new Kibana](https://amo-kibana.prod.mozaws.net/_plugin/kibana/app/kibana#/discover?_g=()&_a=(columns:!(_source),index:'amo*',interval:auto,query:(match_all:()),sort:!(Timestamp,desc))). The old one is still active but won't be around for much longer.

I have a PR for switching to pino (#5826) and a pino transport almost ready :)

Mozlog is a no-go however... It is a complete logger that leverages an older logger (intel) without a way to use their formatter...

See: https://github.com/willdurand/pino-mozlog (WIP/quick & dirty)

To try it:

• checkout the code https://github.com/willdurand/pino-mozlog
• cd pino-mozlog
• yarn && yarn link
• cd addons-frontend
• yarn link pino-mozlog && yarn
• apply this patch:

Now, start yarn amo:dev and you should see the mozlog logs.
