OK: slave redis is connected properly to master|master_last_io_seconds_ago=4;0;0;0

If slave connectivty was broken due to some reasons that it raised an alert.

[ugur@test]# python check_redis_slave.py -H <slave-redis-host> -P 6383
Critical: slave redis server is failed to connect master.It is down!

Tested with

Icinga2 + Redis 2.8.19 - Redis 3.2.1 Cluster
I think that it should be fine with the nagios based software.
