guihecheng 35d40c65f8 Add role definitions of ceph-rgw-loadbalancer ... This add support for rgw loadbalancer based on HAProxy and Keepalived. We define a single role ceph-rgw-loadbalancer and include HAProxy and Keepalived configurations all in this. A single haproxy backend is used to balance all RGW instances and a single frontend is exported via a single port, default 80. Keepalived is used to maintain the high availability of all haproxy instances. You are free to use any number of VIPs. A single VIP is shared across all keepalived instances and there will be one master for one VIP, selected sequentially, and others serve as backups. This assumes that each keepalived instance is on the same node as one haproxy instance and we use a simple check script to detect the state of each haproxy instance and trigger the VIP failover upon its failure.
