The ceph-agent role was used only for RHCS 2 (jewel) so it's not
usefull anymore.
The current code will fail on CentOS distribution because the rhscon
package is only avaible on Red Hat with the RHCS 2 repository and
this ceph release is supported on stable-3.0 branch.

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.

(cherry picked from commit 35d40c65f8)
For ceph-iscsi-gw and ceph-rbd-mirror roles the group_name are named
differently (by default) than the role name so we have to change the
script to generate the correct name.

Problem: the meta declaration just includes the role, it does nothing
with the group_vars. For ansible to use files defined in group_vars/ the
name of the file must match a host group. Like mons, osds, etc. There is
no group docker-common so the variables defined there are never used, as
proved by https://bugzilla.redhat.com/show_bug.cgi?id=1447179 and the
ansible documentation.
Solution: bring the ability to merge roles files. So now by default,
ceph-docker-common and ceph-common will go into all.yml.sample

This adds a script, generate_group_vars_sample.sh, that generates
group_vars/*.sample from roles/ceph-*/defaults/main.yml to avoid
discrepancies between the sets of files. It also converts the line
endings in the various main.yml from DOS to Unix, since generating the
samples was spreading the line ending plague around to more files.
