Improved logging

[larskendall]

Overview

We're currently using for all of our logs, which doesn't give us much control over how and when to display logs. This causes a readability issue in tests, since they can become littered with logs which can't be selectively hidden.

Acceptance Criteria

• Logging should be wrapped in a module to allow the logging library to be easily refactored.
• It should be possible to hide logs based on their log level
• It should be possible to apply custom formatting to log output
