Thundernetes allocation service currently works by finding a random StandingBy server and transitioning it to Active. We should consider the pros/cons of this approach and decide on alternative allocation methods, taking into account the environment that thundernetes is running (cloud provider/on-prem).

Moreover, the use of .Update to transition the game server to Active will return errors in case the GameServer has been deleted or crashed and the cache has not been updated. We should retry ourselves (at least once) in the allocation method.
