Class exception for each metadata module + handler to map on graphql
error
TODO left :
- find a way to call handler on auto-resolvers nestjs query (probably
interceptors)
- discuss what should be done for pre-hooks errors
- discuss what should be done for Unauthorized exception
Fixes#5276.
Updates were not triggering a cache version incrementation because they
do not trigger migrations while that is where the caching version logic
was.
We have decided to move the cache incrementation logic to the services.
