Intent dialog prototype *DO NOT MERGE*

[Stevenic]

Description

Prototype of a new IntentDialog class for review. Sample usage:

const recognizer = new LuisRecognizer(settings);
const dialog = new IntentDialog('agePrompt', recognizer)
     .sendActivityIntent('Begin', `What is your age?`)
     .sendActivityIntent('Help', `Enter a number from 1 to 100`)
     .sendActivityIntent('None', `I'm sorry I didn't recognize your input. Please enter a number.`)
     .endDialogIntent('Cancel', -1)
     .onIntent('Age', async (intent) => {
          const age = intent.recognized.entities.age;
          if (typeof age === 'number' && age > 0 && age < 101) {
              return await intent.endDialog(age);
          } else if (intent.turns >= 3) {
              return await intent.endDialog(-1);
          } else {
              await intent.context.sendActivity(`Enter a number from 1 to 100`);
          }
          return Dialog.EndOfTurn;
     });
