Feature: OAuth2 scope at operation level

[arbs-io]

Many thanks for an amazing liberary. I would like to know if there is a way so scope oauth2 at operation level. The default behaviour seems to apply all scopes to each operation.

example

path:

        "security": [
          {
            "OAuth2": [
              "ApiStudio.Prototype.ApiName.ResourceCollection1.Read",
              "ApiStudio.Prototype.ApiName.ResourceCollection1.Write"
            ]
          }

securitySchemes

      "OAuth2": {
        "type": "oauth2",
        "flows": {
          "implicit": {
            "authorizationUrl": "http://api-studio.io/oauth2/token",
            "scopes": {
              "ApiStudio.Prototype.ApiName.ResourceCollection1.Read": "ApiStudio.Prototype.ApiName.ResourceCollection1.Read",
              "ApiStudio.Prototype.ApiName.ResourceCollection1.Write": "ApiStudio.Prototype.ApiName.ResourceCollection1.Write"
            }
          }
        }
      }

I would really appreciate the ability to apply the scope(s) that are actually used to protect the operation, not all. This is also useful for API gateway that parse the spec to extract which claim is used for security.
