fix [SPARK-740] block manage UI throws exception when enabling Spark Streaming

Because of Spark Streaming's input block naming format (input-xx-xx) is different from Spark (rdd_xx_xx), so block manager UI will throw exception when group this block using block name, detailed thing is illustrated in [\[SPARK-740\]](https://spark-project.atlassian.net/browse/SPARK-740).

Currently I add a key filter to filter out all the Spark Streaming's input block RDD, so the UI will only display processed RDD. Also I sort RDDInfo by RDD's id, so it is clear to see in the UI.
