Activity Feed TSV for use by project-wide visualization

[djbrooke]

We'd like to use the search API to populate an "activity feed" from all dataverse installations. The proposal is to use the existing search API and populating a tsv in the metrics aggregator that could then be leveraged by some visualization to show activity around datafile/dataset/dataverse publishing. The advantage of this approach is that we would only need to add new code in this repo instead of adding a new API endpoint(s) for installations.

As I showed @erikbuunk and told @djbrooke I wrote some code to data on the most recent 7 days (configurable) of published dataveses and datasets across all installations using the Search API. It needs to be cleaned up but here it is: cfad3d9

@djbrooke indicated that we'll take this issue off the board for now. I'll let him decide whether to close it or move it to another column.

Along the way I finally created IQSS/dataverse#6264 to close IQSS/dataverse#2291 so I hope API users get some immediate value out of how to do searches across a data range.
