SPARK-CORE [SPARK-3651] Group common CoarseGrainedSchedulerBackend
variables together
from [SPARK-3651]
In CoarseGrainedSchedulerBackend, we have:
private val executorActor = new HashMap[String, ActorRef]
private val executorAddress = new HashMap[String, Address]
private val executorHost = new HashMap[String, String]
private val freeCores = new HashMap[String, Int]
private val totalCores = new HashMap[String, Int]
We only ever put / remove stuff from these maps together. It would simplify
the code if we consolidate these all into one map as we have done in
JobProgressListener in https://issues.apache.org/jira/browse/SPARK-2299.
