injectCommand does not handle 'dial'

[davehorton]

Say an inbound application wants to queue the caller and separately launch a dial. This requires injectCommand to support 'dial' which it currently does not

[davehorton]

example

      /* queue the caller */
      session
        .say({text: 'Please hold while we find you an agent.'})
        .enqueue({name: session.call_sid})
        .hangup()
        .send();

      await sleepFor(500);

      /* now outdial to the agent, passing on the queue name */
      session.injectCommand('dial', {
        application_sid: 'a52d6cbf-3a8b-41f7-a8d4-4b1964c52451',
        from: '15083728299',
        to: {
          type: 'phone',
          number: '15083084809'
        },
        tag: {
          queueName: session.call_sid,
          prompt: 'Hi there, we have a John Doe on the line.  Please hold and I will connect you'
        }
      })

minimally, need to add something like this to inject-commands.json (but need additional properties)

  "dial": {
    "properties": {
      "application_sid": "string",
      "actionHook": "string",
      "confirmHook": "string",
      "amd": "object",
      "from": "string",
      "to": "object",
      "timeout": "number",
      "tag": "object"
    },
    "required": [
      "application_sid",
      "from",
      "to"
    ]
  }
