Benoît Knecht 97066a1ebc ceph-rgw-loadbalancer: Fix keepalived master selection
While 2ca33641 fixed a bug in the way the `keepalived.conf.j2` template matched
hostnames to set the VRRP `MASTER`/`BACKUP` states, it also introduced a
regression in the case where `virtual_ips` is a list of more than one IP
address.

The previous behavior would result in each host in the `rgwloadbalancers` group
to be `MASTER` for one of the `virtual_ips`, but the new behavior caused the
first host to be `MASTER` for all the IP address in `virtual_ips`.

This commit restores the original behavior.

Alex Schultz 7ddbe74712 Use ansible_facts
It has come to our attention that using ansible_* vars that are
populated with INJECT_FACTS_AS_VARS=True is not very performant.  In
order to be able to support setting that to off, we need to update the
references to use ansible_facts[<thing>] instead of ansible_<thing>.

guihecheng c52020a4db 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.
