If no stdout/stderr requested tell Kubernetes not to send it

[jacobtomlinson]

In cases where you want to write stdout from an exec to a file you may want to avoid also storing that output in the stdout attributed. Especially in cases where this will be large. This PR adds a capture_output kwarg to disable this.

Note

This behaviour is the inverse of subprocess.run() which disables capturing by default.

import kr8s, tempfile

pod = kr8s.objects.Pod.get("my-pod")

with tempfile.TemporaryFile(mode="w+b") as tmp:
    pod.exec(["date"], stdout=tmp, capture_output=False)
