Breaking changes

For a data source query made via /api/ds/query :

• If the DatasourceQueryMultiStatus feature is enabled and
  • The data source response has an error set as part of the DataResponse, the resulting HTTP status code is now 207 Multi Status instead of 400 Bad gateway
• If the DatasourceQueryMultiStatus feature is not enabled and
  • The data source response has an error set as part of the DataResponse, the resulting HTTP status code is 400 Bad Request (no breaking change)
