Bug 1576088

Document URL: https://docs.openshift.com/container-platform/3.9/install_config/install/advanced_install.html#adv-install-example-inventory-files

Section Number and Name: SINGLE MASTER, SINGLE ETCD, AND MULTIPLE NODES

Describe the issue: One of the keys in this JSON is wrong-

#openshift_master_identity_providers=[{'name': 'htpasswd_auth', 'login': 'true', 'challenge': 'true', 'kind': 'HTPasswdPasswordIdentityProvider', 'filename': '/etc/origin/master/htpasswd'}

Suggestions for improvement: 
Remove the 'filename' key and value.

Additional information: 
If you uncomment and use this line, you'll get this error-
