kubectl: check rule in exec command is insecurity

[hunshcn]

What happened?

https://github.com/kubernetes/kubernetes/blob/b53b9fb5573323484af9a19cf3f5bfe80760abba/staging/src/k8s.io/kubectl/pkg/cmd/exec/exec.go#L208-L215

kubectl exec -it resource asd asd asd -- bash will be like kubectl exec -it resource -- bash but no error

This can lead to unexpected behavior of command with --

What did you expect to happen?

raise error error: exec [POD] [COMMAND] is not supported anymore.

How can we reproduce it (as minimally and precisely as possible)?

kubectl exec -it resource asd asd asd -- bash

Anything else we need to know?
