When retiring a connection ID, an endpoint remembers a sequence number and
maybe a packet number for a RETIRE_CONNECTION_ID frame.  An endpoint SHOULD
limit the state it commits to remembering connection IDs that need to be
retired to at least twice the active_connection_id_limit. An endpoint MAY
choose to treat having too many connection IDs in need of retirement as a
connection error of type CONNECTION_ID_LIMIT_ERROR.
