Support for case classes with generic type parameters

For example for:

```scala
case class Response[T](data: Seq[T], pageInfo: PageInfo)
```

where only couple of concrete types are used and registered, for example:

```scala
openAPIModelRegistration.register[Response[A]]
openAPIModelRegistration.register[Response[B]]
```

we could generate number of OpenAPI schema components equal to the number of concrete types, for example with naming convention `______...__`, so in this case `Response__A` and `Response__B`.
