> Current way of fetching new status or information from all experiment pods is 
> to use listExperiments and passing it with status = null, and it will also 
> update the database when pod is being deleted.
> But to display the current condition in k8s, workbench needs to request 
> server every several seconds, which is inefficient and brute-force.
> We can utilize the informer to get the change in k8s then use websocket to 
> tell the workbench what happend.
