Proposal: ZeroLog support and new Logger interface

[nicolerenee]

Proposal

I'm proposing that we switch to ZeroLog as the default logger, so we would want to add a zerologx package that provides config and everything around logging.

Things to do

• Implement zerologx
  • Provides config options for log level (info, warn, debug, trace, etc)
• Implement logging interface
  • x packages should use an interface for logging instead of a specific logger implementation so that you can bring your own logger as long as it matches the interface. The interface can look like zerolog's logger since that is our default and it will make life a little easier.
• Switch x packages to use new logging interface
