DATAREDIS-372 - Allow easier RedisSentinelConfiguration setup.

Browse Source 
We now allow to initialize a RedisSentinelConfiguration based on a given String collection of host:ports.
  sentinelHostAndPorts[0] = 127.0.0.1:23679
  sentinelHostAndPorts[1] = 127.0.0.1:23680

Further on it’s possible to pass in a PropertySource containing master name and sentinel nodes.
  spring.redis.sentinel.master=myMaster
  spring.redis.sentinel.nodes=127.0.0.1:23679,127.0.0.1:23680

Original pull request: #126.
