Support cancelling MultiplayerService session joining functions

Is your feature request related to a problem? Please describe.
It takes several seconds to join a session through MultiplayerService. I'd like to let users cancel a connection attempt during the connection process.

Describe the solution you'd like
I'd like to pass cancellation tokens to functions like MultiplayerService.Instance.CreateOrJoinSessionAsync.

Describe alternatives you've considered
I've tried preventing the NetworkManager from connecting to a session if my own connection function wrapping MultiplayerService.Instance.CreateOrJoinSessionAsync is cancelled, but I cannot find a clean way to do this. I have also considered modifying the Unity.Services.Multiplayer package myself, but I would rather not do this.

Aucun fichier ni test n’est nommé. Commencez par suivre MultiplayerService.Instance.CreateOrJoinSessionAsync et le flux de connexion de NetworkManager afin de comprendre où un jeton d’annulation devrait être propagé. Le travail est terminé lorsque les utilisateurs peuvent annuler la jonction à une session en cours via les fonctions de MultiplayerService sans avoir à modifier eux-mêmes le package.
