It's not possible to get logs during command construction

[soltysh]

What happened:
While preparing for KubeCon EU SIG CLI presentation I've wanted to show how users can see the logs when using kubectl preferences.
So I've run:

KUBECTL_KUBERC=true kubectl -v=5 get po -A

with an empty $HOME/.kube/kuberc file, hoping to see this message
https://github.com/kubernetes/kubernetes/blob/bdda0a530ed26fd5b9f389ae4333a748de861f32/staging/src/k8s.io/kubectl/pkg/kuberc/marshal.go#L99
but sadly I didn't get any. I started looking around and due to how we create commands we only initialize logging when running command.

What you expected to happen:
I'd like to see the output for all log messages even during command construction.

How to reproduce it (as minimally and precisely as possible):

KUBECTL_KUBERC=true kubectl -v=5 get po -A

I spent some time on this issue today. This is not specific to kuberc. For example, kubectl should be able to print a log in this line https://github.com/kubernetes/kubernetes/blob/990b02bf3952a14249fe74add831a5bb02576995/staging/src/k8s.io/kubectl/pkg/cmd/cmd.go#L534 but it doesn't.

I believe that after moving the log initialization into command executions (perhaps with this commit kubernetes/kubernetes@21d1bcd?), we lost the ability to printing logs during command preparation.

I tried to enable it but couldn't have achieved yet.
