How reproducible:

Always 

Steps to Reproduce:

1. Install OCP on upi-on-osp using 4.5.3-x86_64

Actual results:

The OCP installation fails on openstack due `machine-config` operator is Degraded and time out.

level=info msg="Cluster operator machine-config Available is False with : Cluster not available for 4.5.3"
level=fatal msg="failed to initialize the cluster: Cluster operator machine-config is still updating" 

Expected results:

The OCP installation should not fail on OpenStack due to any operator degrade or time out issue.
