Matt McEuen fcaacf94a3 Add -e to pre_stop hooks
This adds -e to the pre_stop scripts, so that they fail out if
any of their commands fail.  This is required, since it's the only
way to communicate whether there is an issue during pre_hook
execution.

"The logs for a Hook handler are not exposed in Pod events.
If a handler fails for some reason, it broadcasts an event."
https://kubernetes.io/docs/concepts/containers/container-lifecycle-hooks/#container-hooks

As an example, this issue was discovered when "touch /tmp/stop"
was failing silently due to a readOnlyRootFilesystem setting,
resulting in pods that would not successfully Terminate until
the grace period was exhausted.
