Browse Source 
Automatic merge from submit-queue (batch tested with PRs 53580, 55568). 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>.

Replace sets.List() with sets.UnsortedList() in pkg/proxy

**What this PR does / why we need it**:

Replace sets.List() with sets.UnsortedList() in pkg/proxy - sets.List() will sort the result array, we don't need sorted array in pkg/proxy. Using sets.UnsortedList() can reduce the unnecessary overhead spending.

**Which issue(s) this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close the issue(s) when PR gets merged)*:
Fixes #

**Special notes for your reviewer**:
