Add ability to turn off notifications, etc. upon group creation

[wesley-dean-flexion]

As an organizational admin, so that I know that the synchronized teams is automatically managed, so notifications aren't sent to everyone, etc., I would like the ability to set various settings when the group is created.

{
  "name": "Justice League",
  "description": "A great team.",
  "privacy": "closed",
  "notification_setting": "notifications_disabled"
}

(there are other settings, but those are the most interesting at the moment)
