We have already refactored _FailoverRegion.java_ to support fail-over with state when using region-failover strategy in our production environment. I'll organize related code to crate a new PR in these days.

> RestartPipelinedRegionStrategy does not perform any state restore. This is big problem because all restored regions will be restarted with empty state. We need to take checkpoints into account when restoring.
