v2 logger

[lavoiesl]

Significant refactor of the logger package.

Design principles / Motivation

The behaviour added by this package should be available outside of this package (via hooks), but it shouldn't force its registration globally.

New features

1. Is it now possible to register a Hook on the logrus StandardLogger, such that the field extraction behaviour can be available.
2. It is now possible to attach a logger on a context, such that the global loggers or the package loggers to not have to be overridden when testing
3. A DuplicateLogger is now available to facilitate duplicating a logrus.Logger

Breaking changes

1. Valuer is removed in favour of the ubiquitous context.Context
2. Remove support for errors.Cause, using errors.Join from go 1.20 instead.

Minor changes

1. Change log-based tests to use text output where it made sense or otherwise remove them
