Data Federation support
Data Federation means that files are not ingested into OSDU, links to the files (external data sources) and file metadata are ingested.

This user story can be split into 2 sub-stories:
1. External datasource is located in another OSDU instance
2. External datasource is not in OSDU
Acceptance Criteria:
What is the acceptance criteria:
- Delivery API can return files
OR
- Search returns returns search results according to the indexed metadata
Questions:
- There may be problems with implementing Scenario 2: External datasource is not in OSDU. This scenario conflicts with OSDU principles regarding data governance, immutability of data and data change control. Data governance approach has to be clarified before development can start.
