Sends a keepalive/heartbeat signal across RPC while a game is running. Server-side this enables the ability to manage play session state with realtime information instead of hoping that the client will stop the play session. Keepalives are tracked in server cache allowing for future potential horizontally-scaled server instances.
Settings for the server are now combined with the settings from the SDK. This introduces a large breaking change and a migration should be created. This refactor utilizes .NET Configuration and the Options pattern. This will allow for the overriding of any setting using envionment variables. It also means that Settings.yml can be used to override any .NET configuration. A SettingsProvider implementation was created, and any updating of settings was changed from SettingsService.SaveSettings() to SettingsProvider.Update(s => { ... })
