Description of problem:

Deleting a rhods-notebook pod for a running application is disruptive and causes immediate termination of the notebook. The same scenario will occur during node maintainance (node/machine reboots)

Prerequisites (if any, like setup, operators/versions):

Setup a RHODS cluster using stage with build v1.1.1-44

Steps to Reproduce

1) Login as one of the configured used (eg: ldap-admin1)
2) launch a minimal python notebook using RHODS Console
3) Run a simple program in loop (the one shown in the screenshot)

4) Find the pod associated with the user and delete pod
eg:

$ oc delete pod jupyterhub-nb-ldap-2dadmin3 -n rhods-notebooks
pod "jupyterhub-nb-ldap-2dadmin3" deleted

$ oc get pods -n rhods-notebooks
No resources found in rhods-notebooks namespace.

5) Notice the pod is not recreated and the program stop immediately with keyboard interrupt.
