Create an OSEv3 group that contains the master, nodes, etcd, and lb groups.
The lb group lets Ansible configure HAProxy as the load balancing solution.
Comment lb out if your load balancer is pre-configured.
Set variables common for all OSEv3 hosts
uncomment the following to enable htpasswd authentication; defaults to DenyAllPasswordIdentityProvider
Native high availbility cluster method with optional load balancer.
If no lb group is defined installer assumes that a load balancer has
been preconfigured. For installation the value of
openshift_master_cluster_hostname must resolve to the load balancer
or to one or all of the masters defined in the inventory if no load
balancer is present.
apply updated node defaults
host group for masters
host group for etcd
Specify load balancer host
host group for nodes, includes region info
