Switch cinder uniquePodNames to true for DCN deployments

This patch reverts the work done in [1], where uniquePodNames
was added as a kustomization parameter for cinder and switched
to false due to [2].
In addition, this patch fixes the way extraMounts Ceph secrets
are accessed, and removes the not required "projected" key.
