redis sentinel is restarted each redeploy

[Radosław Piliszek]

Redis Sentinel modifies its config. Since we now check config in check-containers, the redis_sentintel container is restarted each time.

Due to Ansible quirk with handlers, this causes redis itself to restart as well.

This implies a small unnecessary downtime and possible loss of cache but it's back online in a snap so it's not critical.
