Add staging boolean option to LuisRecognizerOptions

[mattmazzola]

From what I see there is no way to configure the LuisRecognizer to use the staging deployment slot.

It needs to construct the url with the staging=true query parameter; however, there no option in LuisRecognizerOptions for staging.

I looked into submitting PR to add the boolean; but the request url is generated inside the LuisClient which is constructed from a swagger file and that needs to understand the staging option.

• Update botframework-luis swagger to have staging query parameter
• Regenerate client
• Add staging: boolean to LuisRecognizerOptions

This is actually related to issue #77. The currently used Swagger file is very out of date. I think the plan is to pursue creating a NPM library through the Azure-sdk-for-node with the Azure-approved Swagger file and then in botbuilder-ai create a depedency on that library; similar to what is done in Microsoft.Bot.Builder.Ai for the LuisRecognizerMiddleware class.

I was about to make the same comment. The swagger used was out of date. We should get this issue resolved and the LUIS client updated this week.
