seata1.4连接redis, 并发流量下 key值一直增加，异步回收太慢，性能持续下降

[hcs142437]

有哪个版本修复或者压测过嘛

升级1.6.1及以上，调整query-limit参数进行缓解。
实际原因就是由于异步线程只有1个，而业务线程是50个。
Upgrade to version 1.6.1 or higher and adjust the query-limit parameter to mitigate the issue.
The actual reason is that there is only one asynchronous thread, while there are 50 business threads.

有对应的核心改动pr嘛？ seata我们基于1.4魔改了，目前升级可能有点风险； 想把核心的pr或fix合并下
