Igniters, please help me to clarify the following questions: 1). According to the issue [1] we should propagate services deployment results to an initiator, that means we should wait for wor Service#init method completion. How should we handle Service#init method hangup? I propose to introduce some kind of IgniteSystemProperties#IGNITE_SERVICE_INIT_TIMEOUT to interrupt long initialization.
2) Should we automatically undeploy services, which had been deployed using #deployKeyAffinitySingleton, on destroying of related IgniteCache? Thoughts?
