      Description of problem:

      Setting a MachineSet's replicas to "0" does not remove all workers.

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

       

      How reproducible:

       

      Steps to Reproduce:

      Scale a machineset to zero replicas:

```
oc -n openshift-machine-api patch "$(oc -n openshift-machine-api get machineset -o NAME | head -n1)" \
    --type='json' \
    --patch='[ {"op": "replace", "path": "/spec/replicas", "value": 0} ]'
```

      Actual results:

      watch worker nodes decrease to one:

```
oc get nodes
```

and worker instances decrease to one:

```
openstack server list
```

      Expected results:

      Worker nodes scale to zero, OpenStack machines named "worker" scale to zero.
