[Flink-1686] Streaming Iterations Slot Sharing Fix
Iteration head instances were using the same identifier for slot sharing
which resulted into incorrect execution for streaming iterations. I had to add
a unique identifier for each iteration node to fix the issue. They are now
working properly judging from the parallel iterations test.
