The endpoints controller store the resource version of the previous Endpoints objects to avoid issues related to stale information on the cache since #125675

However, there can be update operations that succeed without increasing the resource version, causing the endpoints controller to declare stale the existing Resource Version and stopping the Endpoints to be updated.

I'm fuzzy on the things that can trigger a no-op write, but the resourceVersion comparison looks right to me
