PR #290 missed the update permission to persistentvolumes.
Without that permission, you will get the following error when attaching a RBD volume to a pod:
```
Warning FailedAttachVolume 100s (x11 over 7m52s) attachdetach-controller AttachVolume.Attach failed for volume "pvc-d23f8745-60bb-11e9-bd35-5254001c78d6" : could not add PersistentVolume finalizer: persistentvolumes "pvc-d23f8745-60bb-11e9-bd35-5254001c78d6" is forbidden: User "system:serviceaccount:kube-system:rbd-csi-provisioner" cannot update resource "persistentvolumes" in API group "" at the cluster scope
```
currently we are deploying external-attacher
as a seperate statefulset, which leads to
attacher communicating with the node provisoner
daemonset, This PR deploys external-attacher
as a sidecar container inside provisioner
statefulset, so that external-provisioner
always communicates with the plugin responsible
for the provision controller capcabilities.

remove unwanted rules and update
rbac to have permission to modify
endpoints and configmaps in the
current namespace.
