> Project: Flink
> Issue Type: Sub-task

> Logical pipelined region partitioning is needed by FLINK-14060 to determine
> JobVertex slot sharing group.
> We can leverage PipelinedRegionComputeUtil#computePipelinedRegions to do this
> by adapting JobGraph to a base Topology.
> With changes from FLINK-14453, we can build {{LogicalPipelinedRegions}} from
> {{JobGraph}} by:
> 1. Introduce LogicalTopology which extends Topology
> 2. Implement DefaultLogicalTopology as an adapter of JobGraph to
> LogicalTopology
> 3. Add DefaultLogicalTopology#getLogicalPipelinedRegions to return the
> logical pipelined regions of a JobGraph
