## Context
Deprecating the old objectMetadataMap type in favour of split flat
entities to match with our new caching.
In the long run, trying to achieve:
- Better performance through caching
- Consistent data access patterns across the codebase
- Reduced database queries
Now that everything is based on flat entities, which are cached, we can
finish the refactoring of workspace context cache which should already
improve performances.
Then the last step will be to consume that new cache in the new global
datasource to get rid of the many workspace datasources stored in the
server

There's a huge test bundle in the latest shard that we could split up
## Notes
- Set as failing morph relation field rename as for the moment we do not
handle relation field mutation
- fixed the object update and creation validation adding label
identifier field metadata id checks
- and more
Some integrations tests are still on the v1 ( they have before and after
all disabling and re-enabling the flat ) but mainly we now have more
coverage on the v2 than the v1.
Mainly related records, uniqueness have to be migrated the v2 and so
tests too
