### Search before asking - [X] I had searched in the [issues](https://github.com/apache/dolphinscheduler/issues?q=is%3Aissue) and found no similar feature requirement. ### Description Adding `exclusive worker` field for default worker group in `t_ds_worker_group` table to exclude the specific worker. Why: in DS 3.1.3 version, all active workers will add to `default` worker group. But in same scenarios, like remote worker, it's a specific environment to run the specific tasks. The remote worker may not be suitable for all tasks, some dispatched tasks to the worker will cause error since environment issue. I think common users need not consider about choose which worker group when run tasks, if admin could exclusive some inapplicable worker for `default`, then all rest of worker in `default` worker group is usable. This will be nice for common user. 在 DS 3.1.3 版本中，DS 会将所有存活的`workerNodeInfo`添加到`default`分组，这会导致一个问题： 前提：remote worker 的环境是特殊的，只能执行特定的任务，而普通用户在配置任务时，不应该考虑选择什么 worker 分组，应该无脑默认`default`即可。 问题：`default`中包含的 remote worker 如果不被排除，则任务很可能会被调度到此 remote worker 从而**导致任务因为环境问题失败**，这是很低级的问题。 **解决方案：** 在`t_ds_worker_group`表中添加`exclusive_worker`字段，**含义：被排除的 worker 地址，逗号分隔。** 注意：仅`default`分组可以修改此字段，且`default`分组不可删除。 **影响：** 1. **新注册 worker 时（active worker）** 检测 active worker 是否在`exclusive_worker`中存在，存在则从default分组的`workerNodeInfo`排除，否则添加。 2. **前端需要修改 worker 分组的编辑逻辑：**  ### Use case _No response_ ### Related issues _No response_ ### Are you willing to submit a PR? - [X] Yes I am willing to submit a PR! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
