RedisAutoConfiguration doesn't use server details set in properties file if using pooled connection

[adnansorg]

If using custom redis properties in the application.properties or yaml equivalent, RedisAutoConfiguration doesn't use these settings when using RedisPooledConnectionConfiguration.redisConnectionFactory ().

if (this.properties.getPool() != null) {
    JedisConnectionFactory factory = new JedisConnectionFactory(
            jedisPoolConfig());
    return factory;
}

It needs to set the factory config from properties file.

if (this.properties.getPool() != null) {
    JedisConnectionFactory factory = new JedisConnectionFactory(
            jedisPoolConfig());
    factory.setHostName(this.properties.getHost());
    factory.setPort(this.properties.getPort());
    if (this.properties.getPassword() != null) {
        factory.setPassword(this.properties.getPassword());
    }                
    return factory;
}

Otherwise it uses JedisConnectionFactory defaults which is always localhost and throws connection errors if you're using something other than localhost.
