Zendesk Mobile: show Zendesk new ticket from App Ratings > Send Feedback.

[ScoutHarris]

Fixes #9213

NOTES:

• Your local .wpcom_app_credentials must be up-to-date as it contains Zendesk credentials. If you have not, refer to the Field Guide for instructions.
• SupportSourceTag.inAppFeedback is not passed on to Zendesk. This will be addressed with a future task that implements SourceTag support.

To test:

• Since displaying the App Feedback view is dependent on many conditions, it probably won't just appear. My suggested hack - in NotificationsViewController:showRatingViewIfApplicable comment out the first guard that checks shouldPromptForAppReview. The App Feedback view will always show, but at least you'll see it!
• Go to the Notifications tab.
• Select 'Could Be Better'.
• Select 'Send Feedback'.
• Verify the Zendesk ticket view is displayed.
