currently, in the cluster-test yaml, file we have both cephCluster
CR and cephBlockPool CR and we're trying to update the cephCluster
CR to disable the livnessProbe of mon, osd, mgr but since we had `yq write -d1`
it was updating the second instance of `spec` which is cephBlockPool
instead we have to do `yq write -d0` to update the cephCluster `spec`.
