dashboard: Add provenance info (origin, revision)
Display the origin, revision and release available data if the provenance information is available in nodes_data objects (currently one way is to launch the scanner scan command with the --interactive option and the --extra-info=origin).
If the provenance information is not available in nodes_data objects and the current result page show a known content, a get provenance button is displayed. It calls a dedicated http api endpoint that call the provenance api with the corresponding swhid, and then display the provenance information.
The MR also add an overlay loader with a spinner used with dom loading and http api query.
