It's impossible to use openshift-origin-rhel to create a cluster

openshift-origin-rhel https://github.com/Azure/azure-quickstart-templates/tree/master/openshift-origin-rhel

### Issue Details

I've tried to create a cluster using this template , but I always get an error on OpenshiftDeployment resource

STATUSMESSAGE{
"status": "Failed",
"error": {
"code": "ResourceDeploymentFailure",
"message": "The resource operation completed with terminal provisioning state 'Failed'.",
"details": [
{
"code": "DeploymentFailed",
"message": "At least one resource deployment operation failed. Please list deployment operations for details. Please see https://aka.ms/arm-debug for usage details.",
"details": [
{
"code": "Conflict",
"message": "{\r\n \"status\": \"Failed\",\r\n \"error\": {\r\n \"code\": \"ResourceDeploymentFailure\",\r\n \"message\": \"The resource operation completed with terminal provisioning state 'Failed'.\",\r\n \"details\": [\r\n {\r\n \"code\": \"VMExtensionProvisioningError\",\r\n \"message\": \"VM has reported a failure when processing extension 'deployOpenShift'. Error message: \\\"Enable failed: failed to execute command: command terminated with exit status=2\\\".\"\r\n }\r\n ]\r\n }\r\n}"
}
]
}
]
}
}
RESOURCE
OpenShiftDeployment

### Repro steps
1. Create your keyvault etc
2. deploy the Arm template

Start with the openshift-origin-rhel template linked in the issue and inspect the OpenShiftDeployment resource and deployOpenShift VM extension failure. Review the deployment operation details and extension logs to identify the exit-status-2 cause. Done means the ARM template can create the cluster without the reported provisioning failure.
