fix(crud): take into account Swagger meta defined on overridden methods

For example, allow specifying Swagger metadata this way:

```typescript
export class SomeController {
  @OverRide()
  @ApiOperation({
    title: 'Get list of something',
    operationId: 'getSomething',
  }),
  @ApiOkResponse({ type: Something })
  public getMany() {}
}
```
