What would you like to be added?

In #128266, we are introducing a new /resize subresource to request pod resource resizing. It would be good add support for this in kubectl.

Few options:

1. A new resize subcommand:

kubectl resize pods <pod-name> -c <container> --cpu <cpu> --memory <memory>

2. support for resize subresource in existing commands like kubectl patch and kubectl edit:

kubectl patch pod pause \
     -p '{"spec":{"containers":[{"name":"pause", "resources": {"requests": {"cpu": "200m"}}}]}}' \
    --subresource=resize

kubectl edit pod pause --subresource=resize

Why is this needed?

This will help us manually test this feature as well as making it user friendly to use the new subresource.
