> The following scenario will ended up with termination failed error continuously.
> AS asks CC to create a container
> CC schedule a new task and returning member contexts to AS
> AS adding the members to pending list
> CC is also adding member contexts to its data holder
> But CC will not add it to the topology until pods status become to "Running" state
> Meanwhile members are exceeding their timeouts and moved to obsolete list
> AS asks CC to terminate obsolete pods
> CC kills it, but didn't send the member terminated event, because member is not in the topology
> AS didn't get any member terminated event, so it will not remove any members from its member lists
> AS will ask CC again to terminate the pod, in next monitor interval
> CC now will complain "Failed to terminate member. Member id not found", because it terminated those pods already and removed the member contexts from its data holder
> So this "Failed to terminate member. Member id not found" will occur continuously
