Add upvote/downvote fields to merge request and note API to preserve compatibility
As discussed in !1825 (merged) we should not break the API compatibility.
- This MR adds the fields
upvotes
/downvotes
to the merge request API again, which always return0
. - Add the fields
upvote
/downvote
to the notes API, which always returnfalse
This behavior is documented in the API docs.
This needs to go into 8.2 @rspeicher @vsizov
