ceph-rgw-loadbalancer: Modify keepalived master selection 

Currently the keepalived template only works when system hostnames exactly match the Ansible inventory name. If these are different, all generated templates become BACKUP without a MASTER assigned. Using the inventory_hostname in the template file resolves this issue.
