[SPARK-7598] [Deploy] Add aliveWorkers metrics in Master
In Spark Standalone setup, when some workers are DEAD, they will stay in
master worker list for a while.
master.workers metrics for master is only showing the total number of
workers, we need to monitor how many real ALIVE workers are there to ensure the
cluster is healthy.
