Feature and motivation

Ruby has a great logging implementation, that allows us to easily output warnings, deprecations and for users to toggle level to get things like command path, payload, and header info.

I believe that some of this functionality is available in other bindings, but we don't have it well documented how to toggle it. The solutions need to be language idiomatic, but I'm hoping we can ensure relatively equivalent functionality with this.

Usage example

In Ruby a user can do this to get all info about commands sent to and from the driver or server

Selenium::WebDriver.logger.level = :info
