-- Updates game session properties. This includes the session name, maximum
-- player count, protection policy, which controls whether or not an active
-- game session can be terminated during a scale-down event, and the player
-- session creation policy, which controls whether or not new players can
-- join the session. To update a game session, specify the game session ID
-- and the values you want to change. If successful, an updated
-- < GameSession> object is returned.
