Change the title of the proposal to only include the
proposed new feature. The new title of the proposal
will now be "Expose Idleness Information for Jupyter

The backend will need to be able to create objects with dry-run, in

fails to be created, and the PVCs are never garbage collected.

* notebooks: Handle events gracefully

The controller is not exiting the reconciliation loop after it has
re-emitted a Pod/STS Event as a Notebook Event. This results in the
controller to later on try and GET a Notebook with the name of the Event
that triggered the reconciliation loop.

The controller should exit the reconciliation function once it has

We don't want to trigger the reconciliation function when an event gets
