[SPARK-5593][Core]Replace BlockManagerListener with ExecutorListener in ExecutorAllocationListener

More strictly, in ExecutorAllocationListener, we need to replace onBlockManagerAdded, onBlockManagerRemoved with onExecutorAdded,onExecutorRemoved. because at some time, onExecutorAdded and onExecutorRemoved are more accurate to express these meanings. example at SPARK-5529, BlockManager has been removed,but executor is existed.
