Type Alias DistributionContext 

pub type DistributionContext = PlanContext<bool>;

Keeps track of distribution changing operators (like RepartitionExec, SortPreservingMergeExec, CoalescePartitionsExec) and their ancestors. Using this information, we can optimize distribution of the plan if/when necessary.
