Add a post-install,post-upgrade Helm-hook Job that reconciles the
operator-supplied `users[]` list into the tenant cluster:
- For every entry, apply a ClusterRoleBinding labelled by the
release (managed-by=cozystack-oidc, instance=<release>).
`role: admin` maps to `cluster-admin`; `role: view` maps to
`view`. The subject is the literal `email` value, matched
against the issuer's `preferred_username` claim.
- Prune any orphan CRBs with the same labels — removing a user
from `users[]` revokes their kubectl access on the next loop.
For `mode: System` the same Job also writes
`<release>-oidc-kubeconfig` on the management cluster: a ready
kubeconfig with the per-cluster apiserver endpoint, the tenant CA
extracted from the Kamaji-issued admin kubeconfig, and a
`kubectl oidc-login` exec block keyed to the per-cluster client.
A pre-delete cleanup Job removes the labelled CRBs before the
control plane is torn down (best-effort: the CRBs disappear with
the tenant cluster anyway).
Pod is labelled `policy.cozystack.io/allow-to-apiserver: "true"`
so Cilium lets it reach the konnectivity tunnel.
ServiceAccount/Role/RoleBinding are minimum-privilege — only the
specific admin-kubeconfig and OIDC kubeconfig Secrets are listed.
Renders nothing for `mode: None`.
