Set up logging

[concaf]

We don't log. We should log.

Let's decide on a logging package and start using it for different level of logs. We can consider -

• google/glog
• sirupsen/logrus
• log from stdlib
• juju/loggo
• uber-go/zap

:+1: for sirupsen/logrus

edit: https://github.com/google/glog is in c++, so nah

I don't really see need for logging right now to be honest

If there is no good reason I would stick with stdlib

@cdrage - both Kubernetes and OpenShift use it, worth considering I think.

@kadel - I think we should start doing at least debug logs sooner than later, it'd really help in debugging, etc.

I don't think they support structured logging :(
