### Description of PR When node labels are enabled, different labels represent separate resource pools. However, the RM REST API `/ws/v1/cluster/metrics` currently exposes fields such as totalMB and totalVirtualCores based on the default partition only. As a result, resources from non-default partitions are not visible to external resource management systems, which may incorrectly determine that the cluster has no available capacity after new labels are added. The API should expose cluster resource metrics across all partitions and provide partition-level metrics so clients can distinguish capacity and usage by node label. ### How was this patch tested? unit test and test in cluster based on internal hadoop version. ### For code changes: - [ ] Does the title or this PR starts with the corresponding JIRA issue id (e.g. 'HADOOP-17799.
