Replace klog with a new logging library

[dramich]

This issue is to gather feedback on a replacements for klog

Currently klog presents us with some challenges:

1. The way it parses args see here
2. It's slow (this is known and part of the reason k8s is moving to structured logging backed by zap)

Proposed solution:

1. Update our log package to use this new library and where a logger struct is referenced move to https://github.com/go-logr/logr
2. Replace klog inside the log package with https://github.com/rs/zerolog.
3. Move all direct calls to klog over to the log library

I'm on board! A couple of questions:

1. Do we need logr? I'm not familiar with the library or where we would apply it.

2. Since zerolog supports structured logging, do you have any recommendations for what fields to log and when?

Not sure what the lift is here, but would this be a good potential addition for 1.94?

Klog also has another major problem: kubernetes/klog#212

I believe this has been addressed in #1178. I'm going to close this issue -- feel free to reopen if needed.
