proflin d52bf47e13 [SPARK-12304][STREAMING] Make Spark Streaming web UI display more fri… 
…endly Receiver graphs

Currently, the Spark Streaming web UI uses the same maxY when displays 'Input Rate Times& Histograms' and 'Per-Receiver Times& Histograms'.

This may lead to somewhat un-friendly graphs: once we have tens of Receivers or more, every 'Per-Receiver Times' line almost hits the ground.

This issue proposes to calculate a new maxY against the original one, which is shared among all the `Per-Receiver Times& Histograms' graphs.
