Add exec function to run commands inside pod

[matrus2]

Hi,

It might be useful to have possibility to execute a command inside a pod by a single build-in function during for instance network testing.

Thanks

Hi @matrus2. Thanks for your PR.

I'm waiting for a kubernetes-sigs member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.

I notice there is a failing test not related to the change I introduced, I will look if this can be improved.
