Is your feature request related to a problem? Please describe.

The Java Spring (server side) generator supports generating an API using the delegate pattern with or without the use of tags as names for the generated classes. Tags do not work for a Kotlin Spring API.

Describe the solution you'd like

Allow tags to be used as names of the generated classes (the useTags option)

Describe alternatives you've considered

None

Additional context

This is very useful for the creation of versioned APIs.
