// Places a request for a new game session in a queue. When processing a placement
// request, Amazon GameLift searches for available resources on the queue's
// destinations, scanning each until it finds resources or the placement request
// times out. A game session placement request can also request player sessions.
// When a new game session is successfully created, Amazon GameLift creates a
// player session for each player included in the request. When placing a game
// session, by default Amazon GameLift tries each fleet in the order they are
// listed in the queue configuration. Ideally, a queue's destinations are listed in
// preference order. Alternatively, when requesting a game session with players,
// you can also provide latency data for each player in relevant Regions. Latency
// data indicates the performance lag a player experiences when connected to a
// fleet in the Region. Amazon GameLift uses latency data to reorder the list of
// destinations to place the game session in a Region with minimal lag. If latency
// data is provided for multiple players, Amazon GameLift calculates each Region's
// average lag for all players and reorders to get the best game play across all
// players. To place a new game session request, specify the following:
// - The queue name and a set of game session properties and settings
// - A unique ID (such as a UUID) for the placement. You use this ID to track
// the status of the placement request
// - (Optional) A set of player data and a unique player ID for each player that
// you are joining to the new game session (player data is optional, but if you
// include it, you must also provide a unique ID for each player)
// - Latency data for all players (if you want to optimize game play for the
// players)
//
// If successful, a new game session placement is created. To track the status of
// a placement request, call DescribeGameSessionPlacement (https://docs.aws.amazon.com/gamelift/latest/apireference/API_DescribeGameSessionPlacement.html)
// and check the request's status. If the status is FULFILLED , a new game session
// has been created and a game session ARN and Region are referenced. If the
// placement request times out, you can resubmit the request or retry it with a
// different queue.
