Add the `check` option to server definitions to enable basic HAProxy health
checks for Ceph RADOS gateway backends.
Currently traffic will be forwarded to unhealthly `radosgw.service` servers.
These changes resolve the issue.

The vrrp_instances variable is using a loop with index but the index_var
wasn't defined.
As a result, the fact task was failing on this undefined index variable.
The task includes an option with an undefined variable. The error was:
'index' is undefined

The ad7a5da commit introduced a regression when using TLS on haproxy
via the haproxy_frontend_ssl_certificate variable.
This cause the "stats socket" and the "tune.ssl.default-dh-param"
parameters to be on the same line resulting haproxy failing to start.

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.

This patch also changes the ansible log_path value via the
ANSIBLE_LOG_PATH environment variable in the travis configuration to
avoid warnings.

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.
