[GitHub] [dubbo] jk-tonycui opened a new pull request, #10412: add default interval for retries of saving properties
jk-tonycui opened a new pull request, #10412:
URL: https://github.com/apache/dubbo/pull/10412
## What is the purpose of the change
为了解决issue列表中 https://github.com/apache/dubbo/issues/10402 的问题，该问题主要描述如下：
AbstractRegistry.doSaveProperties()虽然采用文件锁、版本号以及重试等方式对竟争场景做了处理，但是在竟争文件锁失败创建重试任务时，没有sleep，仍会有概率出现上一个版本保存操作还没有释放锁，新版本重试次数达到上限导致新版本数据没有保存到cache文件的情况。
## Brief changelog
改动点主要是将默认共享线程池 SharedExecutor 换成了 SharedScheduleExecutor 以支持增加默认的延迟，避免快速重试导致上述问题出现。
也考虑过通过实现类似Spring-Retry方式实现，但对于现有结构改动较大且收益不高，所以采用 ScheduleExecutor 方式改动
## Verifying this change
<!-- Follow this checklist to help us incorporate your contribution quickly and easily: -->
## Checklist
- [x] Make sure there is a [GitHub_issue](https://github.com/apache/dubbo/issues) field for the change (usually before you start working on it). Trivial changes like typos do not require a GitHub issue. Your pull request should address just this issue, without pulling in other changes - one PR resolves one issue.
- [ ] Each commit in the pull request should have a meaningful subject line and body.
- [ ] Write a pull request description that is detailed enough to understand what the pull request does, how, and why.
- [ ] Check if is necessary to patch to Dubbo 3 if you are work on Dubbo 2.7
- [ ] Write necessary unit-test to verify your logic correction, more mock a little better when cross module dependency exist. If the new feature or significant change is committed, please remember to add sample in [dubbo samples](https://github.com/apache/dubbo-samples) project.
- [ ] Add some description to [dubbo-website](https://github.com/apache/dubbo-website) project if you are requesting to add a feature.
- [ ] GitHub Actions works fine on your own branch.
- [ ] If this contribution is large, please follow the [Software Donation Guide](https://github.com/apache/dubbo/wiki/Software-donation-guide).
