Description

The legacy RestartPipelinedRegionStrategy has been superseded by AdaptedRestartPipelinedRegionStrategyNG in Flink 1.9.
It heavily depends on ExecutionGraph components and becomes a blocker for a clean scheduler re-architecture.

Since it is basically broken and is not a public interface(the failover config "region" now points to AdaptedRestartPipelinedRegionStrategyNG), it's safe to remove it.

I'd propose to remove the legacy RestartPipelinedRegionStrategy components to reduce efforts for further changes on flink runtime.
