Review comment:
`getConfiguration()` may be empty when executing sql jobs and will make
this fix ineffective in that case. This problem seems to be caused by
`DummyStreamExecutionEnvironment` which does not properly override
`getConfiguration()`. But we are still looking into some details to figure out
whether it is safe to fix it by simply do the overriding.

Review comment:
Maybe `useDynamicGraphSourceParallelism` is more accurate because
conceptually `isAdaptiveBatchSchedulerEnabled == getConfig().isDynamicGraph()`.
