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.

So, we will mark that one as solved, it does what it is said to do: reload when app start.
