Updates to the EDU Directory viewer

SDS is splitting the Organization page into two new pages: People and Groups. This reflects a more modern UI, aligned closer to the familiar experience found in the Office 365 Admin Center. Under the new People page, you can see all the Students, Teacher, and Parents synced into Office 365 by SDS. Under the Groups view you can see all the Schools, Classes, and Security Groups you created and synced to Office 365 through SDS. There is also a simple search and filter pane to help you quickly find the EDU objects and attributes you're looking for for simplified sync troubleshooting.
