I have already done a preliminary review for you, and I hope to help you do a better job.

Based on the pull request title and the diff, it seems that the changes are related to enabling the pull_integration_realcluster_test in the latest-presubmits.yaml file for the tikv/pd repository. Specifically, the changes are setting always_run to true and removing optional flag.

It is difficult to identify potential problems without any description or context about the changes made in this pull request. However, a potential problem could be that the pull_integration_realcluster_test is not stable yet and setting always_run to true and removing optional flag could lead to frequent failures or delays in the CI/CD pipeline.

As a fixing suggestion, the pull request author could provide more context and information about the stability of the pull_integration_realcluster_test and if there are any known issues. Additionally, they could consider keeping the optional flag until the test is stable and consistently passing.

I have already done a preliminary review for you, and I hope to help you do a better job.

Based on the pull request title and the diff, it seems that the changes are related to the CI/CD pipeline for the Tikv project's PD component. Specifically, the changes are making the real cluster test run by setting always_run to true and optional to true.

There are no potential problems with the changes in the pull request, but there is a missing description which makes it difficult to determine what the changes are intended to do.

As a fixing suggestion, the pull request should include a detailed description of the changes made and why they are necessary. This will help future reviewers and contributors to better understand the purpose of the changes.
