Throw should be assignable on specific actions

[brizzbuzz]

Hola,

Right now, it appears that .throws() is only actionable on the Route... curious what people think about also allowing throws to be assigned at the individual get, post, actions. For example, right now I can do

route("/example").throws(exe1, exe2) {
  get { .. }
  post { .. }
}

However, since get/post quite often will have differing exceptions, it would be useful to be able to assign throws documentation to the individual actions, ie

route("/example") {
  get().throws(exe1) { .. }
  post().throws(exe2) { .. }
}

Dug further into the code, this functionality is achievable instead through the NormalOpenApiRoute DSL like so

route( "/example") {
  throws(exe1) {
    get { .. }
  }
  throws(exe2) {
    post { .. }
  }
}
