Redis: adding annotation and service type to redis setup (#2586)

Browse Source 
* Adding service type and service annotations to redis

* redis: bumping the redis version

*    [stable/redis]
   Adding service.annotations and service.loadBalancerIP to readme. I see mix naming conventions that is confusing but still I try to do the change in a backward compatible manner

*    [stable/redis] bumping the version to 1.0.3
