Create supporting teams using existing ArcGIS Online groups

[Anneka_France]

At the moment, you can add a new supporting team (creates a new ArcGIS Online group) or you can add an existing supporting team that was created for another hub initiative. However, we would like an option to add an existing ArcGIS Online group as a supporting team.

This would be especially useful where we are transitioning some of our existing data collection projects into Hub Premium, so that we can avoid having to migrate the members and content to a new group; which can cause confusion for existing users, and also requires us to update our automated scripts (which we use to assign and manage group members).
