[DSIP-64] Add more workflow Integration test cases in master.

### Search before asking

- [X] I had searched in the [DSIP](https://github.com/apache/dolphinscheduler/issues/14102) and found no similar DSIP.

### Motivation

After https://github.com/apache/dolphinscheduler/issues/16423, we can easily add integration case for master.
Some cases are already added at #16423, but the workflow might have many structure, and some task might influence the workflow runtime graph, so we need to add more cases.

- Switch task case https://github.com/apache/dolphinscheduler/issues/16725
- Sub workflow task case
- Condition task case
- More failover case
- More workflow operation case
- Master event bus benchmark

### Code of Conduct

- [X] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct)

Start by reviewing the existing integration cases from #16423 and the related switch-task case in #16725. Add and validate coverage for sub-workflow, condition-task, failover, workflow-operation, and event-bus benchmark scenarios; done means the proposed master workflow structures and runtime behaviors have integration coverage.
