This commit adds a configuration option es.nodes.data.only for managing whether or not reads using EsInputFormat and writes using EsOutputFormat in Hadoop MapReduce jobs route through non-data nodes. The reason for wanting to avoid routing through non-data nodes is because these nodes are usually resource-constrainted relative to data nodes. This configuration option is enabled by default. Closes elastic#512
