### Search before asking - [X] I had searched in the [DSIP](https://github.com/apache/dolphinscheduler/issues/14102) and found no similar DSIP. ### Motivation Right now, the log is stored at worker/master and remote server. The query logic look like below <img width="1193" alt="image" src="https://github.com/apache/dolphinscheduler/assets/22415594/a36e3d45-8b9e-4b14-94c7-c298b47d6f9a";> The LogService is duplicate at worker/master, we need to maintain two service implementation which have the same code. And once the master/worker is not active, then we can not fetch the log, this problem may occur frequently in k8s. So it's better to create a LogClient at API side to manage the log fetch logic, and create a LogServer to response for the client request, the LogServer will be imported at master/worker. ### Design Detail <img width="1174" alt="image" src="https://github.com/apache/dolphinscheduler/assets/22415594/91fc2143-102b-4ea0-b5ef-73c92d7d193d";> 1. We will fetch the log from master/worker firstly. 2. If the master/worker not exist or we cannot find the log file from master/worker then we will try to fetch from remote log storage. ### Compatibility, Deprecation, and Migration Plan Compatibility with previous version. ### Test Plan Test by manual. ### 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.
