> Following config options are needed for speculative scheduler:
> * jobmanager.adaptive-batch-scheduler.speculative.enabled, default to "false".  It controls whether to enable speculative execution. Note that speculative execution only works with AdaptiveBatchScheduler, which requires "jobmanager.scheduler" to be set to "AdaptiveBatch".
> * jobmanager.adaptive-batch-scheduler.speculative.max-concurrent-executions, default to "2". It controls how many executions (including the original one and speculative ones) of an ExecutionVertex can execute at the same time.
> * jobmanager.adaptive-batch-scheduler.speculative.block-slow-node-duration, default to "1 min". It controls how long an identified slow node should be blocked for.
