> GMSMembership has a _shunnedMembers_ collection that is used to track the IDs of nodes that are no longer part of the cluster.  This collection is no longer needed since we can tell if a node is old by comparing the view ID in its identifier to that of the current view (called _latestView_ in that class.  Checks like this are already in place in some parts of the code.
> All uses of _shunnedMembers_ should be replaced with this check.
> MembershipView<ID> view = latestView;
> boolean shunned = memberId.getVmViewId() <= view.getViewId() && !view.contains(memberId);
