Description

In the milestone one, we should:

1. Add an extra method (TypeserializeSnapshotr#resolveSchemaCompatibility(TypeSerializerSnapshot<T> oldSerializerSnapshot)) in TypeSerializerSnapshot.java as above, and return INCOMPATIBLE as default.
2. Mark the original method as deprecated and it will use new method to resolve as default.
3. Implement the new method for all built-in TypeserializerSnapshots.

See FLIP-263 for more details.
