yes, but one offer/answer contains a group of candidates. And 
there can be multiple subsequent offer/answers which update 
the set of candidates. Although it is forbidden to remove 
a candidate or reuse its candidate id, it _is_ allowed 
to change candidate properties (priority, type), so simply
adding new remote candidates is not a sufficient API... it must
be possible to update info for the already added remote
candidates as well. And that's how I ended up with
set_remote_candidates()
intead of add_remote_candidate().
