Do not start with ref topo == everything to busbar 1

[BDonnot]

Have a certain type of "action" in each "chronic" folder for that.

This action would be specified by object names and not IDS (to keep backward compatibility with different backends !)

So:

• be able to specify an action by names
• implement the "read action after a reset"
• implement a parameters to disable this behaviour

Done and live in release in 1.10.3
