Remove pod CRUD from getCommonRbacRules.

getCommonRbacRules is used by every component's service-namespace Role, including Ironic, API, inspector, and INA. Pod create and delete are needed only in the console namespace, and getGraphicalConsoleRbacRules already grants them there. This change broadens privileges for all components. Revert the pod rule and update the test that expects three rules.

Update the operator RBAC before reconciling delegated pod Roles.

The controllers call common_rbac.ReconcileRbac with rules that grant full pod management. The operator’s manager-role grants only pods get,list. It has neither roles/escalate nor rolebindings bind.

Kubernetes can therefore reject the delegated Role or RoleBinding with Forbidden, blocking RBAC reconciliation. Add the full pod verbs to all five controller marker sets and regenerate config/rbac/role.yaml. The existing secret and SCC permissions already cover the remaining rules, so escalate and bind are not required after the operator holds the delegated permissions.

Update the RBAC markers for all five controllers—ironicapi, ironic,
ironicconductor, ironicinspector, and ironicneutronagent—to grant pods create,
get, list, watch, update, patch, and delete permissions. Regenerate
config/rbac/role.yaml so the operator’s manager role includes these pod verbs;
do not add roles/escalate or rolebindings bind permissions.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Use a console namespace name that cannot collide.

The prefix truncation maps openstack-a and openstack-b to the same openstack-ironic-consoles namespace. The Role and RoleBinding names depend only on the service account name, so the two deployments can overwrite each other's Role and RoleBinding. The RoleBinding subject namespace is overwritten, which revokes console access for the other deployment. Use the full namespace as the prefix.

Update getConsoleNamespaceName to use the full serviceNamespace as the prefix
instead of truncating it at the first hyphen, so distinct service namespaces
produce distinct console namespace names.

Delete the cross-namespace Role and RoleBinding during cleanup.

These resources have no owner references, and nothing removes them. Cleanup is missing when consoles are disabled and when the CR is deleted. The bindings remain and continue to grant secret and pod access to any later service account with the same name. Add explicit deletion to reconcileDelete and to the disabled path.

Line 1058 replaces instance.Spec.Images.Conductor with quay.io/steveb/...:kubectl for every deployment. That ignores user and release image configuration and pulls from a personal registry.
