Obtain the current group capacity, and the reference IDs for updating load balancers (if any) over RPC from a GroupInspector and the nested stack outputs. Fall back to grouputils (which loads the nested stack in memory) only if the output containing the reference IDs is not available. Change-Id: Ic6909e42edf709ba1cd99ba71f2d2f06570a615f Closes-Bug: #1731349
