This is a clone of issue
OCPBUGS-1226. The following is the description of the original issue:
We added server groups for control plane and computes as part of
OSASINFRA-2570, except for UPI that only creates server group for the control plane.
We need to update the UPI scripts to create server group for computes to be consistent with IPI and have the instruction at https://docs.openshift.com/container-platform/4.11/machine_management/creating_machinesets/creating-machineset-osp.html work out of the box in case customers want to create MachineSets on their UPI clusters.
