OBSINTA-1595: scope alerts adapter RBAC to openshift-lightspeed namespace

[tremes]

Replace ClusterRole/ClusterRoleBinding with namespaced Role/RoleBinding for AgenticRun access. The adapter only creates and lists AgenticRuns in openshift-lightspeed, so cluster-wide RBAC is unnecessarily permissive.

📝 Walkthrough

Summary by CodeRabbit

• Bug Fixes
  • Restricted alerts adapter AgenticRun permissions to the target namespace instead of cluster-wide access.
  • Updated cleanup behavior to remove the corresponding namespace-scoped permissions.
  • Preserved existing Alertmanager cleanup behavior.

Walkthrough

Changes

AgenticRun RBAC scope

Layer / File(s)	Summary
Deploy namespace-scoped RBAC hack/quickstart/deploy-alerts-adapter.sh	The script creates an AgenticRun Role and RoleBinding in ${NAMESPACE}.
Undeploy namespace-scoped RBAC hack/quickstart/undeploy-alerts-adapter.sh	The script deletes the namespace-scoped RoleBinding and Role, and updates failure warnings.

Merge Risk: 🟡 Moderate · up to 22f05

The scripts now create namespaced RBAC, but upgrades do not remove the legacy ClusterRole and ClusterRoleBinding, so existing installations can retain cluster-wide AgenticRun permissions. This concrete security and permission issue should be fixed or explicitly accepted before merge.

Remove legacy cluster-scoped RBAC during upgrade.

When this script runs against an installation created before this change, oc apply creates the Role and RoleBinding but does not delete the existing ClusterRole and ClusterRoleBinding. The old ClusterRoleBinding continues to grant cluster-wide AgenticRun access. Delete the adapter's legacy cluster-scoped resources after the namespaced binding is applied, and retain equivalent cleanup in hack/quickstart/undeploy-alerts-adapter.sh.

Also applies to: 100-110
