> Collect and show the new executor memory metrics for each stage, to provide more information on how memory is used per stage.
> Modify the AppStatusListener to track the peak values for JVM used memory, execution memory, storage memory, and unified memory for each executor for each stage.
> Add the peak values for the metrics to the stages REST API. Also add a new stageSummary REST API, which will return executor summary metrics for a specified stage:
> {code:java}
> curl http://<spark history server>:18080/api/v1/applications/<application id>/<application attempt/stages/<stage id>/<stage attempt>/executorSummary{code}
> This is a subtask for SPARK-23206. Please refer to the design doc for that ticket for more details.
