Resource limits for Pods are missing

[Barteus]

When deploying the Charmed Kubeflow bundle there are no resource limits set up for Pods. This is a good practice to set it up. We can kill a cluster with it by overusing resources, additionally, when LimitRange is impacting the deployment it's really hard to find a root cause. During the deployment, the Pods should refuse to schedule based on the resource required/limit setting and LimitRange.

Thank you for filing this, currently charms don't provide a clear way of setting these configurations. We are studying internally how we can solve this.
