AWS kube-up: Reboot support with ephemeral storage 

If the ephemeral volume is present and mounted, don't try to reinitialize
them.

Don't block the boot if the ephemeral volume is corrupt / missing -
this enables us to cope with a stop/start & presumably also corruption.
In this case, we'll reformat the ephemeral storage.

Fix #21157
