API to add multiple files to the dataset.

[JayanthyChengan]

Hi Team:

At Scholars Portal, as we were integrating Globus with Dataverse for large file transfer, a new API is created to add metadata of multiple files to the dataset. The existing API $SERVER_URL/api/datasets/:persistentId/add gives us limitation since it adds only one file to the dataset.

Once the files are transferred to S3 bucket, the new API /addfiles is invoked with “jsonData” (an array containing the files information)

jsonData:

[{"description":"","directoryLabel":"","restrict":"false","storageIdentifier":"s3://gcs5-bucket1:179a489cb24-769e2d9456fc123","fileName":"1951b.csv","md5Hash":"0056bf95d5f98ab9a930e38b69c14295","mimeType":"text/comma-separated-values"},{"description":"","directoryLabel":"","restrict":"false","storageIdentifier":"s3://gcs5-bucket1:179a489cb24-ed5edbe7b75fa","fileName":"BooksTDRv2a.pdf","md5Hash":"0cabd29624c9ea80d32c0355418197ba","mimeType":"application/pdf"}]

API call:
curl -X POST -H 'X-Dataverse-key: $API_TOKEN' "$SERVER_URL/api/datasets/:persistentId/addFiles?persistentId=#PERSISTENT_IDENTIFIER" -F 'jsonData=$JSON_DATA'

I will submit pull request for this issue.

Huh. PR #7901 was merged but the automatic close didn't happen. Closing! Thanks for the PR, @JayanthyChengan!
