Automatic reload python script
Reload script: note all inconsistencies

If a single node has a desired value more recent and different that the
cluster value, only this node will report the local inconsistency.
Other nodes' desired value can be more recent but identical to the
cluster value.
In such case, multiple nodes updated their file (with regard to the
cluster settings timestamp), but don't agree in the desired value.
The script now report such case.

Also print source and inconsistencies of effective setting.
