Improve Difference Output

[joe-elliott]

Currently the logger just directly writes the output of https://github.com/go-test/deep. In most cases this is fine, but not great.

When changing the image for a deployment:

[Template.Spec.Containers.slice[0].Image: grafana/loki:master-61b5bc6 != grafana/loki:master-20bb95f]

In some cases it produces difficult to understand output. When changing memory limits:

[Template.Spec.Containers.slice[0].Resources.Limits.map[memory]: {{838860800 0} {} BinarySI} != {{209715200 0} {} BinarySI}]
