"Stopping K3s" page is misleading

[sylvainfaivre]

Discussed in k3s-io/k3s#8382

Hello,

Following the discussion linked above, I think this whole documentation page should be moved and redone : https://docs.k3s.io/upgrades/killall

There is no sense having this page in the upgrades section (as it is not needed for upgrades), maybe it could be a new docs section, or a paragraph in the FAQ ?

This page could also be expanded to give general instructions about stopping and starting the k3s service (without killing the pods) with a paragraph dedicated to the killall script as a special case.
