Connect to RedisCluster with password auth

Currently it is not possible to connect to RedisCluster with password. AUTH param is described in documentation (last example) https://symfony.com/doc/current/components/cache/adapters/redis_adapter.html#configure-the-connection but totally ignored in the code and connection fails ``` RedisAdapter::createConnection( 'redis:?host[localhost]&host[localhost:6379]&host[/var/run/redis.sock:]&auth=my-password&redis_cluster=1' ); ``` See RedisCluster usage here https://github.com/phpredis/phpredis/blob/develop/cluster.markdown#declaring-a-cluster-with-an-array-of-seeds
