We had discussed RETIRE_KEYS in Tokyo, and this PR attempts to write that up.

RETIRE_KEYS is an explicit signal allowing peers to agree on when to discard unused keys. It simplifies the text for discarding initial keys and allows efficiently discarding handshake keys without requiring timers or risking deadlocks (#2214).

I believe this is simpler to reason about than the KEYS_ACTIVE proposal (#2237) and safer as it makes less assumptions about the handshake protocol.
