Current behavior

The Open API schema type name is the same as the type name.

Expected behavior

Add a decorator to allow specification of a schema type name that is different from the type name.

For example:

@ApiSchema({ name: 'MyType' })
class MyTypeDto {
}

Minimal reproduction of the problem with instructions

What is the motivation / use case for changing the behavior?

Type names often have suffixes such as Entity or Dto that represent internal implementation choices. Allowing explicit specification of the schema type name would avoid leaking these choices into the public interface.
