TaskHubClient and TaskHubWorker need public access to instance of InstanceStore service

We need in many solutions access to instance store IOrchestrationServiceInstanceStore within TaskHubClient and TaskHubWorker.

For example :
taskHubClient.InstanceStore.GetJumpStartEntitiesAsync();
taskHubWorker.instanceStore.GetJumpStartEntitiesAsync();

Alternatively, you could provide same methods on hub APIs:

taskHubClient..GetJumpStartEntitiesAsync();
taskHubWorker.GetJumpStartEntitiesAsync();

Thanks
