Subject: Initial HA master

- Ability to specify multiple masters
  - configures the CA only a single time on the first master
  - creates and distributes additional certs for additional master hosts

- Depending on the status of openshift_master_cluster_defer_ha (defaults to
  False) one of two actions are taken when multiple masters are defined
  1. If openshift_master_cluster_defer_ha is true
     a. Certs/configs for all masters are deployed
     b. openshift-master service is only started and enabled on the master
     c. HA configuration is expected to be handled by the user manually after
        the completion of the playbook run.
  2. If oepnshift_master_cluster_defer_ha is false or undefined
     a. Certs/configs for all masters are deployed
     b. a Pacemaker/RHEL HA cluster is configured
        i. VIPs are configured based on the values of
           openshift_master_cluster_vip and
           openshift_master_cluster_plublic_vip
        ii. The openshift-master service is configured as an active/passive
            cluster service
