When submitting a ProvisioningRequest using a ClusterTemplate that bypasses hardware provisioning by specifying bmcCredentialsDetails, the ClusterInstance fails to render with the following error:

$ oc get provisioningrequest
NAME                                   DISPLAYNAME             AGE   PROVISIONPHASE   PROVISIONDETAILS
123e4567-e89b-12d3-a456-426614174000   sno-baremetal-okd-aio   59m   failed           Failed to render and validate ClusterInstance: failed to validate the rendered ClusterInstance with dry-run: failed to apply ClusterInstance: failed to create typed patch object (sno-baremetal-okd-aio/sno-baremetal-okd-aio; siteconfig.open-cluster-management.io/v1alpha1, Kind=ClusterInstance): .spec.nodes[0].bmcCredentialsDetails: field not declared in schema

    Consistently reproducible when bypassing hardware provisioning.

    1. Define ClusterTemplate containing bmcCredentialsDetails under NodeSpec properties
    2. Submit ProvisioningRequest referencing above ClusterTemplate
    

    ClusterInstance fails to render

    ClusterInstance renders and ProvisioningRequest progresses to cluster installation
