deploy: fix cephLogDir passing to storageclass via helm

Browse Source 
cephLogDir: is a storage class option that is passed to rbd-nbd daemon.
cephLogDirHostPath: is a nodeplugin daemonset level option that helps in
                   using the right host-path while bind-mounting

In case if you need a customized log path, you should do below:
- Edit the daemonset templates to change the `cephLogDir`
- If you are using helm charts, then you can use key `cephLogDir`
- Edit the daemonset templates to change the ceph log directory host-path
- If you are using helm charts, then you can use key `cephLogDirHostPath`
```
helm install --set cephLogDir=/var/log/ceph-csi/my-dir
helm install --set cephLogDirHostPath=/var/log/ceph-csi/my-dir
```
- For standard templates edit [csi-rbdplugin.yaml](../deploy/rbd/kubernetes/csi-rbdplugin.yaml)
