Discover member clusters from MemberCluster CRs and their per-cluster credential Secrets, keeping the legacy member-list ConfigMap + mounted kubeconfig as a fallback. A watcher restarts the operator on MemberCluster add/change/delete. Grant the base role get/list/watch on memberclusters.

Summary
Slice 3 of the multi-cluster installation-UX epic. The operator now discovers member clusters by reading
MemberClusterCRs and their per-cluster credential Secrets from its own namespace (keyed byspec.clusterName), instead of the MCK 1.xmongodb-kubernetes-operator-member-listConfigMap + monolithic mounted kubeconfig. The legacy path is kept as a fallback (used when noMemberClusterCRs exist) so existingsetup-driven E2E stay green; it's removed in a later slice.A
MemberClusterwatcher (mirroring theOperatorConfigwatcher) restarts the operator on CR add/spec-change/delete. No-restart reactivity is deferred to a later slice — see the decision +multicluster-runtimeevaluation note indocs/dev/multi-cluster-config-tooling.md. The base role gainsget/list/watchonmemberclusters.Interim limitations (tagged
TODO(m1kola): slice-3): in-place credential rotation needs an operator restart; the failover health-checker's file-based cache doesn't apply on the CR path (guarded).Proof of Work
