create should override existing service

[misohu]

Why it needs to get done

This change is affecting edge case:

When user is trying to create a notebook wile the service with the same name exists the dss will not allow that. Steps to reproduce.

pip install .
export DSS_KUBECONFIG=~/.kube/config  # assuming config is set
dss initialize 
kubectl create service clusterip empty-service --tcp=80:9376 -n dss
dss create empty-service --image=pytorch

output:

2024-04-19 11:55:53 [INFO] [main] [create_notebook_command]: Executing create command
2024-04-19 11:55:53 [ERROR] [create_notebook] [create_notebook]: Failed to create Notebook. Notebook with name 'empty-service' already exists.
Please specify a different name.
2024-04-19 11:55:53 [ERROR] [utils] [get_service_url]: Failed to get the URL of notebook name with error code 404.
Check the debug logs for more details.
2024-04-19 11:55:53 [DEBUG] [utils] [get_service_url]: Failed to get the URL of notebook name with error: services "name" not found

Instead of the existing behavior the dss create should override existing service.

What needs to get done

dss create can create notebooks in dss namespace even if services with the same name already exist. These services will be overridden.

When is the task considered done

Functionality is implemented and tested.
