resource-agents package with redis agent. v1 none

Description Eoghan Glynn 2015-02-04 16:11:24 UTC 
We need an RA for redis, as OpenStack Ceilometer uses redis as the backend for the olso.tooz coordination library.

A native liveness monitoring and mastership failover scheme is provided by redis in the form of redis-sentinel.

However, after discussions with fabbione it was decided not to use that and instead to rely on pacemaker across the board.

I have verified that the redis resource agent is included in 
resource-agents-3.9.5-50.el7.x86_64.

[root@virt-150 ~]# rpm -ql resource-agents | grep redis
/usr/lib/ocf/resource.d/heartbeat/redis
/usr/share/man/man7/ocf_heartbeat_redis.7.gz

[root@virt-150 ~]# bash -n /usr/lib/ocf/resource.d/heartbeat/redis
