[SPARK-6671] Add status command for spark daemons
SPARK-6671
Currently using the spark-daemon.sh script we can start and stop the spark demons. But we cannot get the status of the daemons. It will be nice to include the status command in the spark-daemon.sh script, through which we can know if the spark demon is alive or not.
