deploy: add csidriver object for cephfs and rbd

csidriver object can be created on the kubernetes
for below reason.

If a CSI driver creates a CSIDriver object,
Kubernetes users can easily discover the CSI
Drivers installed on their cluster
(simply by issuing kubectl get CSIDriver)

Ref: https://kubernetes-csi.github.io/docs/csi-driver-object.html#what-is-the-csidriver-object

attachRequired is always required to be set to
true to avoid issue on RWO PVC.
