Merge pull request #49125 from abgworrall/handle-gke-clusters

Automatic merge from submit-queue (batch tested with PRs 47509, 46821, 45319, 49121, 49125) Tolerate a missing MasterName (for GKE) When testing, GKE created clusters don't provide a `MasterName`, so don't throw a warning and give up when that happens. ```release-note NONE ```
