Authentication issue with this api

[suman-aella]

This Redis Util doesn't provide a way to configure password while creating the Redis client.

We get Authentication issue with the same

Request processing failed; nested exception is redis.clients.jedis.exceptions.JedisDataException: NOAUTH Authentication required.

The RedUtilsConfig class needs to accept even the password as a config parameter.

The JedisConnectionManager should be able to intialize the pool with password as parameter.

public JedisConnectionManager(RedUtilsConfig redUtilsConfig) {
        this.capacity.set(redUtilsConfig.getLockMaxPoolSize());

        GenericObjectPoolConfig<Jedis> lockPoolConfig = ConnectionPoolFactory.makePool(capacity.get());
        this.channelConnectionPool = new JedisPool(lockPoolConfig,
                redUtilsConfig.getHostAddress(),
                redUtilsConfig.getPort(),
                redUtilsConfig.getReadTimeOutMillis()
        );
 }

Currently it is passed as null.

public JedisPool(final GenericObjectPoolConfig<Jedis> poolConfig, final String host, int port,
      int timeout, final String password) {
    this(poolConfig, host, port, timeout, password, Protocol.DEFAULT_DATABASE);
}

I can do this change in the RedUtilsConfig and JedisConnectionManager if you are ok with it.
