Deployment of OCP SNO spoke with Telco DU profile via ZTP fails with the
following error in the gitops app:

oc get apps -n openshift-gitops clusters 
wait for gitops clusters and policies apps to be in sync (1 retries left).
        kind: SiteConfig
        message: The Kubernetes API could not find ran.openshift.io/SiteConfig for
          requested resource helix55/site-plan-helix55. Make sure the "SiteConfig"
          CRD is installed on the destination cluster.
        name: site-plan-helix55

The root cause appeared to be a filename collision between an default manifest
and a custom manifest in the ZTP siteconfig.  In this case it was the
siteconfig/sno-extra-manifest/enable-cgroups-v1.yaml manifest. Not sure if the
issue is with this specific manifest only (it was added as a default manifest
in recent ztp-site-generate container builds)

Removing the local file allows deployment to proceed. The error message is
confusing and doesn't indicate the real cause of the failure; the manifest
filename collision.

OCP 4.15.0-rc.3
gitops-rhel8-operator/images/v1.10.1-3
ztp-site-generator:v4.15.0-29

Always

1. Deploy SNO DU node with conflicting manifest filename
2. Observe gitops app status
3.

Error above is shown and install does not proceed

Error message should indicate the case for the failure as a manifest filename
collision.
