Adding docs using utilruntime.Must for scheme registration #894

Merged

In addition to adding scaffolded utilruntime.Must for scheme registration in kubebuilder (kubernetes-sigs/kubebuilder#1462) this updates the docs for controller-runtime docs to include panicking when scheme registration fails.

You will notice that internal to localSchemeBuilder in client-go (https://github.com/kubernetes/client-go/blob/master/kubernetes/scheme/register.go#L133) and most schemes within kubernetes they cause panics if anything from conversions to defaults fail.

After discussing with @DirectXMan12 this being left out probably either an oversight to that this pattern was developed after these packages where made.

@DirectXMan12 What is best practice using Must for adding scheme?

EDIT: nvm. kubernetes-sigs/kubebuilder#1462 (comment) seems to answer this.
