Automatic merge from submit-queue (batch tested with PRs 59882, 59434, 57722, 60320, 51249). 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>. Expose default service IP CIDR in apiserver **What this PR does / why we need it**: The `--service-cluster-ip-range` parameter of API server is very important for deploying Kubernetes on some clouds. The default CIDR "10.0.0.0/24" should be exposed at least from the API server's help message so that users have a better idea whether they need to change it. This patch exposes this default value in API server's help message. **Which issue this PR fixes** : fixes #51248 **Release note**: ``` NONE ```
