-------------------------------------------

             Summary: Migrate enum serializers to use new serialization compatibility abstractions
                 Key: FLINK-11334
                 URL: https://issues.apache.org/jira/browse/FLINK-11334
             Project: Flink
          Issue Type: Sub-task
          Components: State Backends, Checkpointing, Type Serialization System
            Reporter: Tzu-Li (Gordon) Tai


This subtask covers migration of:
* EnumSerializerConfigSnapshot
* ScalaEnumSerializerConfigSnapshot
to use the new serialization compatibility APIs ({{TypeSerializerSnapshot}} and {{TypeSerializerSchemaCompatibility).

The enum serializer snapshots should be implemented so that on restore the order of Enum constants can be reordered (a case for serializer reconfiguration), as well as adding new Enum constants.

Serializers are only considered to have completed migration according to the defined list of things to check in FLINK-11327.
