Setup relations for remote objects (#5149)

New strategy:
- add settings field on FieldMetadata. Contains a boolean isIdField and
for numbers, a precision
- if idField, the graphql scalar returned will be a GraphQL id. This
will allow the app to work even for ids that are not uuid
- remove globals dateScalar and numberScalar modes. These were not used
- set limit as Integer
- check manually in query runner mutations that we send a valid id

Todo left:
- remove WorkspaceBuildSchemaOptions since this is not used anymore.
Will do in another PR
