Notebook content is removed on every start stop

[Barteus]

Bug Description

When I create a notebook using the default notebook image - charmedkubeflow/jupyter-scipy:v1.7.0_20.04_1

New notebooks are created in the /var/lib/pebble/default instead of the volume that is attached to the Pod under /home/jovyan/

To Reproduce

1. Deploy Kubeflow
2. Create a notebook
3. Open the notebook and create a new ipynb
4. Stop the notebook and start it again
5. File is missing

Expected: Files exists after notebook restart.

Environment

• GCP VM
• microk8s 1.24/stable
• Kubeflow 1.7

Relevant log output

**Notebook**
$ !pwd
/var/lib/pebble/default

This is now fixed in the 1.7/stable bundle. The fix was introduced in
canonical/kubeflow-rocks#61
#314

We'll need to keep this in mind though when creating our ROCKs for 1.8
