Bug report

The k8s executor doesn't save .command.log for each task. This matters because output from beforeScript and afterScript are not saved to .command.out or .command.err, so I can't capture outputs from these directives when using kubernetes. Task logs can be accessed via kubectl logs <pod> but pods are deleted upon completion.

I see that this functionality was added recently in the case of pod failures (#699), I think this behaviour should be extended to pod completions as well.

Alternatively we could change beforeScript and afterScript to also pipe into .command.out / .command.err but I think that would be more complicated.
