Description

This subtask covers migration of:

• StreamElementSerializerConfigSnapshot
• NFASerializerConfigSnapshot
• NullableSerializerConfigSnapshot
• UnionSerializerConfigSnapshot
• TwoPhaseCommitSinkFunction.StateSerializerConfigSnapshot
• TimerSerializerConfigSnapshot
• SharedBufferSerializerConfigSnapshot
• RowSerializerConfigSnapshot
• CompositeSerializer.ConfigSnapshot
• BufferSerializerConfigSnapshot
• ScalaOptionSerializerConfigSnapshot
• ScalaTrySerializerConfigSnapshot
• TrySerializerConfigSnapshot
• OptionSerializerConfigSnapshot
• CollectionSerializerConfigSnapshot
• CRowSerializerConfigSnapshot
  to use the new serialization compatibility APIs (TypeSerializerSnapshot and {{TypeSerializerSchemaCompatibility).

They should use the higher-level CompositeTypeSerializerSnapshot which handles nested serializer compatibility checks.

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