Lee Hinman feb244c14a Remove cluster name from data path
Previously Elasticsearch used $DATA_DIR/$CLUSTER_NAME/nodes for the path
where data is stored, this commit changes that to be $DATA_DIR/nodes.

On startup, if the old folder structure is detected it will be used.
This behavior will be removed in Elasticsearch 6.0

Resolves #17810
