client instance warnings when describe non-existent pod

[mmb]

Describe the issue

If you describe a non-existent pod when using kubelogin it shows warnings:

W0521 10:28:30.795744   51175 exec.go:282] constructing many client instances from the same exec auth config can cause performance problems during cert rotation and can exhaust available network connections; 1402 clients constructed calling "kubectl"
W0521 10:28:30.795964   51175 exec.go:282] constructing many client instances from the same exec auth config can cause performance problems during cert rotation and can exhaust available network connections; 1403 clients constructed calling "kubectl"
W0521 10:28:30.796178   51175 exec.go:282] constructing many client instances from the same exec auth config can cause performance problems during cert rotation and can exhaust available network connections; 1404 clients constructed calling "kubectl"

This is not a real use case but why are so many clients being created?

To reproduce

kubectl describe pod does-not-exist
