Title: KERN-2397 add limited ability for non-managers to update collections

I put a flow chart on the JIRA which explains how this works:
https://jira.sakaiproject.org/browse/KERN-2397

Basically, a non-manager will be given an administrative session to update group membership if the request passes a strict group of conditions.
