Use the new dataset set management endpoints

https://redmine.teklia.com/issues/6264

Requires backend#1712 (closed)

The dataset edition modal should use a table to list all of the sets, as we already do for element types, entity types, etc. Each set can be renamed or deleted, and a new set can be added, through the new CreateDatasetSet, PartialUpdateDatasetSet and DestroyDatasetSet API endpoints.

On dataset processes, the checkboxes that allowed selecting sets within a dataset are removed. The table will now list sets rather than datasets, so there is only one set per row. You can select a project, then a dataset, then a set, and add it. You can remove sets one by one as well.
