Add control for Integrated Calendar Notifications

In the RingCentral App, it would be really beneficial to have the ability to turn off calendar notifications so that entries which exist in the original calendar (Outlook, Gmail) don't send a duplicate notification in Ring Central. At this point, the only way to prevent this is to unlink the calendar (removing the ability to create meeting invites from Ring Central) or mute all notifications (making the soft phone functionality unusuable)
