Increase image shutdown timeout for deployment

[Noah-Huppert]

The server will not shut down until all jobs have finished running.

If the server does not shut down gracefully in some timeout k8s will kill 9 the pod. This will screw up any jobs which are running.

• Increase the timeout to something pretty big, maybe 2 minutes, so that this never happens.
• Look into k8s pods in the terminating state to make sure that no new connections are sent to these pods
  • If new connections are sent to terminating pods then simply setting the timeout to be higher will not be enough. As the server could receive a web hook request and start a new job, which in turn would make the server wait even longer before shutting off, one could imagine a situation where the terminating pod keeps receiving web hook requests and never gracefully shuts down, causing a kill 9
