Add a webhook resource subscription for Groups to notify of membership changes
When a member is added or removed from a group, or when membership is requested, make a call to a webhook that can receive the userid, and the action: add, remove, 'request to join', etc.
We have a lot of processes that hinge upon membership in a group. Instead of constantly polling the group and doing membership comparisons, this would make changes more real-time.

Groups has webhook now on beta endpoint. Was probably added around September.
