Review:

Title: [bug] disttae: fix a UT in route package.

Body: The pull request is labeled as a bug fix and it aims to fix a unit test in the route package. The PR is associated with issue #13943.

Changes:
The changes made in the pull request are in the route_test.go file. The following changes were made:

• Line 70: A new option clusterservice.WithDisableRefresh() was added when creating a new MOCluster instance.

Feedback:

1. The title and body of the pull request are clear and provide sufficient information about the purpose of the changes.

2. The changes made in the pull request seem to be related to a unit test in the route package. However, without the context of the test case and the specific issue being fixed, it is difficult to provide a comprehensive review.

3. The added option clusterservice.WithDisableRefresh() in the NewMOCluster function call should be documented with a comment explaining its purpose and why it is necessary for the unit test. This will help future developers understand the intention behind the code.

4. It is important to ensure that the added option clusterservice.WithDisableRefresh() does not introduce any security vulnerabilities or unintended side effects. A thorough review of the clusterservice package and its usage is recommended to ensure that the option is used correctly and does not compromise the security or stability of the system.

5. It is unclear if there are any other changes made in the pull request apart from the added option. If there are additional changes, they should be clearly documented and explained in the pull request description.

Optimization Suggestions:

1. If there are other changes made in the pull request, it would be helpful to include them in the diff output to provide a complete overview of the modifications.

2. Consider adding more detailed comments in the code to explain the purpose and functionality of the modified code. This will make it easier for future developers to understand and maintain the code.

Overall, the pull request seems to address a specific bug in the route package. However, without more context and information about the specific issue being fixed, it is difficult to provide a comprehensive review. It is recommended to provide more details and explanations in the pull request description to help reviewers understand the changes and their impact. Additionally, thorough testing and security review of the added option clusterservice.WithDisableRefresh() is necessary to ensure it does not introduce any vulnerabilities or unintended consequences.
