Merge pull request #52903 from wackxu/mpi
Automatic merge from submit-queue (batch tested with PRs 53507, 53772, 52903, 53543). If you want to cherry-pick this change to another branch, please follow the instructions <a href="https://github.com/kubernetes/community/blob/master/contributors/devel/cherry-picks.md">here</a>. Make configFactory private **What this PR does / why we need it**: Fix TODO make this private if possible, so that only its interface is externally used. I have check the use of configFactory and it is safe to make it private. **Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes # **Release note**: ```release-note NONE ```
