When installing OpenShift on top of OpenStack, the post-installation management of MachinePools (which translate into MachineSets in the target cluster) is not functioning.

Version-Release number of selected component (if applicable):
lates

How reproducible:
100%

Steps to Reproduce:
1. Install OpenShift onto an OpenStack environment
2. After installation, modify a MachinePool (raise the replica count)
3.

Actual results:
Hive doesn't update the MachineSet definition in the target cluster is not updated to reflect the changes made to the MachinePool.

Tested on registry.svc.ci.openshift.org/ocp/release:4.7.0-0.nightly-2020-11-25-114114
hive commit id: 7a4ece8ca2d02cd619da7

1. Install OpenShift onto an OpenStack environment
2. After installation, modify a MachinePool, change replica count from 3 to 2
$ oc get machinepool lwanosphive-worker
NAME                 POOLNAME   CLUSTERDEPLOYMENT   REPLICAS
lwanosphive-worker   worker     lwanosphive         2

3. check on target cluster, machinesets count scale down from 3 to 2
$ oc get machineset -n openshift-machine-api 
NAME                         DESIRED   CURRENT   READY   AVAILABLE   AGE
lwanosphive-jkc5n-worker-0   2         2         2       2           3h

4. change replica count from 2 to 3 again, check on target cluster, machinesets scale up to 3 again
$ oc get machineset -n openshift-machine-api 
NAME                         DESIRED   CURRENT   READY   AVAILABLE   AGE
lwanosphive-jkc5n-worker-0   3         3         3       3           3h7m
