> {{ScheduledUnit#vertexExecution}} is nullable but {{ProgrammedSlotProvider}}
> requires it to be non-null to work. This makes {{ProgrammedSlotProvider}} not
> able to be used by new scheduler tests since {{vertexExecution}} is never set
> in the new scheduler code path. It blocks us from reworking tests which are
> based legacy scheduling to base on the new scheduler.
> Besides that, there are 2 other problems caused by the nullable
> vertexExecution:
> 1. The log printed in SchedulerImpl#allocateSlotInternal(...) may contain no
> useful info since the vertexExecution can be null.
> 2. NPE issue reported in FLINK-16145.
> Thus I would propose to replace the nullable vertexExecution with a non-null
> executionVertexID.
