pd: make real cluster test run

[ti-chi-bot[bot]]

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.

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.
