[SPARK-7988][STREAMING] Round-robin scheduling of receivers by default
Minimal PR for round-robin scheduling of receivers. Dense scheduling can be
enabled by setting preferredLocation, so a new config parameter isn't really
needed. Tested this on a cluster of 6 nodes and noticed 20-25% gain in
throughput compared to random scheduling.
