Force reload of generic-method cache when app starts
Description
We now have a generic method cache /var/rudder/configuration-repository/ncf/generic_methods.json. For now, there is no built-in logic to auto-regenerate it when generic methods are updated.
Since there is tons of unforseen path on witch generic methods can be updated (from a plugin contributed them to a hack workaround to a bug), it would be very surprising for users to not see their changes, even after an app restart

Actually, we can check even during run time, when generic methods are requested: we have two files (/var/rudder/ncf/{common,local}/ncf_hash_file) that are updated at each agent run et that contain one hash for all methods. We just need to check if that content changed.

On which system did it happened ? Works on several platforms i tested (6.1 mostly ... )

- Fix check changed from Error - Next version to Checked
So, we will mark that one as solved, it does what it is said to do: reload when app start.
We will manage a more reliable system in 7.0 with #18652.
