> FLINK-13550 supported for CPU FlameGraphs in web UI.
> As Flink doc mentioned:
> https://nightlies.apache.org/flink/flink-docs-master/docs/ops/debugging/flame_graphs/#sampling-process
> {code:java}
> Note: Stack trace samples from all threads of an operator are combined
> together. If a method call consumes 100% of the resources in one of the
> parallel tasks but none in the others, the bottleneck might be obscured by
> being averaged out.
> There are plans to address this limitation in the future by providing “drill
> down” visualizations to the task level. {code}
>
> The flame graph at the subtask level is very useful when a small number of
> subtasks are bottlenecked. So we should provide the flame graph to the
> subtask level
