Description of problem:
Setup OCP 3.4 on vsphere, create a cloud.conf with vsphere credentials, enable vsphere cloud provider in node config. After node is restarted, got error "Cloud provider not initialized properly", but there is no clear clue why it was not properly initialized.

Version-Release number of selected component (if applicable):
openshift v3.4.0.21+ca4702d
kubernetes v1.4.0+776c994
etcd 3.1.0-rc.0

How reproducible:
Always

Steps to Reproduce:
1. Install latest ocp with openshift-ansible
2. created /etc/cloud.conf with:
[Global]
        user = [hidden]
        password = [hidden]
        server = [hidden]
        port = 443
        insecure-flag = 1
        datacenter = Datacenter
        datastore = datastore1

[Disk]
        scsicontrollertype = pvscsi


In master-config.yaml set:
  apiServerArguments:
    cloud-provider:
    - "vsphere"
    cloud-config:
    - "/etc/cloud.conf"
  controllerArguments:
    cloud-provider:
    - "vsphere"
    cloud-config:
    - "/etc/cloud.conf"
Then restart master

In node-config.yaml set:
kubeletArguments:
  cloud-provider:
    - "vsphere"
  cloud-config:
    - "/etc/cloud.conf"
Then restart node

Actual results:
Node is restarted successfully but did not become 'Ready', run 'journalctl' and error "Cloud provider not initialized properly" is shown.

Expected results:
Should have cloud provider initialized successfully

Additional info:
Using same cloud.conf in Kubernetes, cloud provider is initialized properly. Not sure what needs to be tuned in ocp
