Allow subscribeRetryWaitTimeMillis to be passed as argument to the JedisSentinelPool

[aosti]

Hello, we are using your library with 1 master, 3 slaves and 4 sentinels in total. The code looks like:
`

    JedisSentinelPool pool = null;  
    Jedis jedis = null;
    String[] s = { ip1:port, ip2:port, ip3:port, ip4:port };
    Set<String> sentinels = new HashSet<String>();
    for (String sentinel : s) { sentinels.add(sentinel); }

    JedisPoolConfig poolConfig = new JedisPoolConfig();
    poolConfig.setMaxTotal(1);   // test configuration
    pool = new JedisSentinelPool("redis-cs-cluster", sentinels, poolConfig);
    jedis = pool.getResource();

    // Test operations
    int i = 0;
    while(true) {
        try {
            jedis.set("test", "a" + i);
            i++;
            Thread.sleep(2000);
        } catch (Exception e) {
            System.out.println(e.getMessage());
            if(jedis != null) {
            	jedis.close();
            }	
            jedis = pool.getResource();
	}
    }

`

After getting the Jedis instance and executing some jedis.set operations, the redis master instance died (killed by us to execute this test), and sentinel executed the failover. However, even after the failover, the MasterListener inside Jedis keeps throwing
Lost connection to Sentinel at 10.210.43.97:16380. Sleeping 5000ms and retrying.: redis.clients.jedis.exceptions.JedisConnectionException: java.net.ConnectException: Connection refused (Connection refused)

after every 5s.
We know from our application, that we won't be able to reactivate that particular instance in less than 1 hour, causing too many messages to be added to the log file.

Is it possible to add subscribeRetryWaitTimeMillis as argument to some constructor of JedisSentinelPool?

We are using Java 8, Jedis 2.9.0 and Redis 3.2.8.

Thank you for your attention!
