Walkthrough

Replaced unified global MCE cluster limit with platform-specific limits for AWS (10) and GCP (10). Updated CreateMceCluster logic to count active clusters separately per platform and enforce independent admission checks. Added helper functions to determine cluster platform via labels or ClusterDeployment specification.

Summary

Platform-Specific MCE Cluster Limits pkg/manager/manager.go, pkg/manager/mce.go

Replaced single global limit (maxTotalMCEClusters=15) with platform-specific AWS (10) and GCP (10) limits. Updated CreateMceCluster to count active clusters per platform separately and enforce independent admission checks with platform-directed error messages. Added mceClusterIsAWS and mceClusterIsGCP helper functions that determine platform via ManagedCluster labels (Cloud field) or ClusterDeployment.Spec.Platform fields, with fallback handling for custom image builds.
