Modification to the prepare-fs script does not lead to a rolling upgrade

[sebgl]

The prepare-fs init container executes the script that exists in a configmap.
Any update to the content of that configmap does not trigger a rolling upgrade of the cluster.

I think it's not exactly expected.
But also not exactly sure whether that's a bug or a feature :| (it could be useful to not upgrade existing clusters for minor modification in the script?).
