title: Swagger Try It Out button without actually making changes
body: <p>I have added Swashbuckle to a new .Net Core Web API to enable Swagger documentation.</p>
  
  <p>Really digging the Try-It-Out option that is provided. </p>
  
  <p>However, is there something in the library that can be checked before calling any underlining business logic?</p>
  
  <p>For example. Take the Try it out on a delete endpoint. I would like to leave the button intact and working, though would not like to actually delete a resource in the event swagger was used to make the call. </p>
