Describe the issue: 

As of v3.10, master api and controllers have been implemented as static pods[0], and their pod have mount point which can be refer the related configuration files, such as master-config.yaml, certificates and cloud provider config files.

So the mount point has limited as "/etc/origin/cloudprovider" in their pod for looking for the cloud provider config files. But the sections in the docs have been written as "/etc/cloud.conf", it's not correct.

Suggestions for improvement: 

The location of config file must be in "/etc/origin/cloudprovider", and the config file also had better to change the config filename as "openstack.conf" like similar section of aws, azure and vsphere.

Additional information: 

Look other cloud provider sections as follows, their config files have been located in "/etc/origin/cloudprovier". Only OpenStack is different path.
