Multiplayer SDK 2.2.0

Multiplayer Session ScriptableObject to hold an `ISession` and expose the session events to the inspector.

Session Connector ScriptableObject to populate the Multiplayer Session ScriptableObject. Create, Join, and CreateOrJoin connectors are available; they include session settings as well as network settings.

Session Connector Wrapper Monobehaviour to automatically execute the specified connector on sign in.

New verbose settings in Project Settings > Services > Multiplayer.

`ISession` created or joined through the `MultiplayerService` in Play mode in the Editor are automatically left when exiting Play mode.

Fixed a bug in the sessions API where if using direct connections and Netcode for GameObjects 2.8 or later, an erroneous endpoint would be used for the connection data, leading to errors about an "invalid listen endpoint" followed by an endpoint with the port duplicated.

Exiting Play mode in the Editor when a Session is connected with Netcode for GameObjects' `NetworkManager` no longer logs warnings.

Fixed wrong Exception handling in the Matchmaker module and the `NetworkMetadata` handler when joining an `ISession` already connected to a `NetworkManager` .

Fixed an issue where matchmaker queue deployment could fail when the queue contains filtered pools.
