--------------------------------

             Summary: Introduce wrapper class to hold information besides ArchivedExecutionGraph
                 Key: FLINK-21188
                 URL: https://issues.apache.org/jira/browse/FLINK-21188
             Project: Flink
          Issue Type: Sub-task
          Components: Runtime / REST
            Reporter: Matthias


Instead of returning only the {{ArchivedExecutionGraph}}, the plan is to introduce a wrapper class {{ExecutionGraphInfo}} that would hold the exception history besides the execution graph.

This change might also be necessary as we could support returning a collection of {{ArchivedExecutionGraphs}} as part of the work on the declarative scheduler ([FLIP-160|https://cwiki.apache.org/confluence/display/FLINK/FLIP-160%3A+Declarative+Scheduler]).
