issue on trident-csi units, not finding TridentBackendConfig CRD

Example from https://gitlab.com/sylva-projects/sylva-core/-/jobs/13054748953:

2026/02/10 13:38:56.659605 Unit timeout exceeded: unit Kustomization/trident-csi-storage-class-ontap-san did not became ready after 5m0s

This happens despite the fact that the trident unit, which is responsible for installing, has reconciled successfully long before the timeout.

The CRD is indeed absent.

Looking more closely, that TridentBackendConfig CRD is not directly installed by the trident-operator Helm chart, it is installed by the operator itself, which in the case here, is failing.

It's failing because it fails to create a transient-trident-version-pod special pod:

2026-02-10T13:33:49Z    2026-02-10T13:35:56Z    kubelet-mgmt-2316602081-rke2-capm3-virt-management-md-0 Pod     transient-trident-version-pod   9       BackOff "Back-off pulling image ""docker.io/netapp/trident:25.10.0"""

This auxiliary pod isn't waited for by the Helm release, so nothing is waiting for it.

To better catch this kind of problem, we should add a trident-ready unit, as a dummy Kustomization unit, with a healthCheck waiting for the presence of the TridentBackendConfig CRD.
