> The ExecutionGraphBuilder registers several metrics directly on the JobManagerJobMetricGroup, which are never cleaned up.
> When the AdaptiveScheduler re-creates the EG these will collide with metrics of prior attempts.
> Essentially we either need to create a separate metric group that we pass to the EG or refactor the metrics to be based on some mutable EG reference.
