[Feature] At present, the metadata pushed by the metadata center does not have an expiration date. When using Nacos as the metadata center, there is still a quantity limit. After switching to Redis as the metadata center, it was found that there is no expiration TTL setting

Also, the Jedis version is too low. Spring defaults to Jedis version 5.0.x, but it's still 3.x. Can we upgrade it

1. We can set TTL for it. But we need a mechanism to refresh it.
2. You can upgrade it in 3.3.x

Currently, the Redis metadata center implementation class of 3.3.0 is being used, but there is no TTL code available. We will continue to monitor future updates

1. We can set TTL for it. But we need a mechanism to refresh it.我们可以为它设置TTL。但是我们需要一种机制来刷新它。
2. You can upgrade it in 3.3.x您可以在 3.3.x 中升级它

Currently, the Redis metadata center implementation class of 3.3.0 is being used, but there is no TTL code available. We will continue to monitor future updates目前，正在使用 Redis 元数据中心实现类 3.3.0，但没有可用的 TTL 代码。我们将继续关注未来的更新

Would you like to contribute for it:)你愿意为它做出贡献吗：）

hello，I think I can solve it, can it be assigned to me, thanks

I don't know what the logic is now. After long-term use, the data will be more and more, and many data have expired. I hope that unnecessary data can be automatically eliminated.
