I think that we need a NEED_MORE_CIDS frame.

The issue I see with the approach proposed in #1465 is that it is hard to determine the number of spare CIDs is an endpoint expected to provide to the peer. I'd assume that 1 as the number of spare CIDs is too small, since if an endpoint tries to probe a path using the spare and fails, it would get out of CIDs.
