title: Redisson eviction on set/map
body: <p>I don't understand how eviction work on set with Redisson.</p>
  
  <p>Thanks to <a href="https://github.com/redisson/redisson/wiki/7.-distributed-collections#731-set-eviction" rel="nofollow noreferrer">the wiki</a>, i can see there is an <code>org.redisson.EvictionScheduler</code>. This worker is supposed to schedule execution to evict old keys in Redis. This method is used to apply TTL on sub-element of a list, and not globally on the key holding the list in Redis. (The TTL on the key list is set to <code>-1</code> by the way)</p>
  
  <p>I can't make this work, the scheduler doesn't seem to execute. Do i have to create some more bean on the spring conf ? Is there any additional things to do ?</p>
  
  <p>I'm using a RSetCache.</p>
  
  <p>to put a value : 
  <code>redisson.getSetCache(key, stringCodec).add(value, lifeSpan, TimeUnit.MILLISECONDS);</code>
  so i'm using this method : <code>org.redisson.api.RSetCache#add</code></p>
