Dataset sets management API endpoints

closes #1720 (closed)

requires !2264 (merged)

EDIT: contrary to what it says in the issue, the endpoints require contributor access to the dataset's corpus, excepted for DELETE which requires admin access.

TODO

• Update Dataset endpoints documentation (no more sets editing there)
