Move `logs` and `certwatcher` from `controller-runtime`

[miparnisari]

Hi there. Our Go repository doesn't need k8s at all but imports the following:

• https://pkg.go.dev/sigs.k8s.io/controller-runtime@v0.21.0/pkg/certwatcher
• https://pkg.go.dev/sigs.k8s.io/controller-runtime@v0.21.0/pkg/certwatcher/metrics
• https://pkg.go.dev/sigs.k8s.io/controller-runtime@v0.21.0/pkg/log

I wonder if they could get moved to this repo to reduce the size of our binary.

Thanks!
