Spark 2017

I address here issues SPARK-2017 and SPARK-2016 by serving the data for the tables as JSON further rendering under Spark UI web interface.

Main addition is exposing paths with the JSON data as:

/stages/stage/tasks/json/?id=nnn
/storage/json
/storage/rdd/workers/json?id=nnn
/storage/rdd/blocks/json?id=nnn

and using javascript to built the tables from an ajax request of those JSON.
