Release Note

The `ListCheckpointed` interface has been deprecated because it uses Java Serialization for checkpointing state which is problematic for savepoint compatibility. Use the `CheckpointedFunction` interface instead, which gives more control over state serialization.

Description

Per discussion in https://github.com/apache/flink/pull/3508, we consider deprecating the `ListCheckpointed` interface to discourage Java serialization shortcuts for state registrations (towards this, the Java serialization shortcuts provided by the `OperatorStateStore` interface have already been deprecated in https://github.com/apache/flink/pull/3508).

We should also remember to update https://ci.apache.org/projects/flink/flink-docs-release-1.2/dev/stream/state.html#using-managed-keyed-state if we decide to do this.
