Operation to ingest a file on one or more pillars in a collection.
A PutFile request is based on the fileID of the file that is to be ingested in a collection.
Prior to the request it is the client's responsibility to ensure that the file is present at the file exchange location. Also it is the clients responsibility to remove it after the operation (if needed).
