 Review comment:
   Had offline discussion with @singlis . The idea was that I thought using Task.Delay will
hold the execution without locking the thread. But actually there is no difference with calling
Thread.Sleep() and Task.Delay().GetAwaiter().GetResult().
   Changed it back to Thread.Sleep()

>            Priority: Major
> After user submits task to Azure Batch runtime, client is not able to communicate REEF
HTTP server hosted on Driver, due to network configuration. We want to save the pain for user
of setting up VNET in Azure Batch Pool to enable the connection.
> We will provide this capability by a HTTP connection proxy, which exchanges HTTP request
through Azure Storage Queue.
