Amplify on launch requests permission for notifications, which is undesirable

Describe the bug When launching an iOS React Native application the user is immediately asked to enable push notifications. This happens, I believe, because Amplify.configure() eventually calls PushNotification.initializeIOS().

To Reproduce Create an iOS React Native application and run Amplify.configure().

Expected behavior Request permission to send notifications later, when needed. e.g., after an onboarding flow, sign-in, etc.

Smartphone (please complete the following information):

• Device: iPhone 8
• OS: iOS 12.0

Additional context

It would be nice if this were removed from PushNotification.initializeIOS():

PushNotificationIOS.requestPermissions({
  alert: true,
  badge: true,
  sound: true
});

And instead were a separate method (e.g., PushNotification.requestPermissionsIOS().

I submitted my own PR #2697 to add this functionality because my team also needs it for our app. I used the config option approach to maintain backward compatibility as requested. Please let me know if it looks ok, @powerful23

The way it works is that you configure PushNotification to not automatically request permissions:

PushNotification.configure({ requestIOSPermissions: false });

Then later when you are ready to request the permission, you can manually call this method:

PushNotification.requestIOSPermissions();

After you allow the permission in the app, the device token will be received by the library.

Hope this helps.

Any progress with this? 😀
