      Description

      ClusterInvalidator implementation based on Redis replacing the SQL one.

      To use it edit the repository contrib and add:

          <clusterInvalidatorClass>org.nuxeo.ecm.core.redis.contribs.RedisClusterInvalidator</clusterInvalidatorClass>

      Invalidations are sent and received using the Redis pubsub messaging on the channel: nuxeo:inval:default:channel.
      (default being the name of the repository)

      There is a Redis HSET created for each Nuxeo node with the following key: nuxeo:inval:default:nodes:<nodeId>

      $ redis-cli
127.0.0.1:6379> keys nuxeo:inval:default:nodes:*
1) "nuxeo:inval:default:nodes:16934"
2) "nuxeo:inval:default:nodes:11424"
127.0.0.1:6379> hgetall nuxeo:inval:default:nodes:16934
1) "started"
2) "2015-08-20T10:22:04.497"
3) "lastInvalSent"
4) "2015-08-20T12:29:10.443"
127.0.0.1:6379> ttl  "nuxeo:inval:default:nodes:16934"
(integer) 86328

      The gain can be seen here (around x2) on heavy write operations:
