[Feature Request] Add ability to generate union type resolver based on __typename field

See original GitHub issue

Is your feature request related to a problem? Please describe. When using union type with graphql-java-codegen, we need to define a way to tell Jackson how to choose which implementation depending on the data. This step could be generated.

Describe the solution you’d like The spec ( defines the __typename field which will be populated with the data type. It would be possible to generate Jackson annotations & resolver based on the __typename field. This behaviour could be linked to a configuration toggle, and could be overwritten by customAnnotationsMapping configuration.

Describe alternatives you’ve considered Stay with current implementation.

In the case a modelPackageName is empty, I see that it defaults to packageName. And if both modelPackageName & packageName, the class will be generated in the default root package.

Ok for the proposed switch name and default value.

I will send a PR soon.

I will give it a try.
