When we use caikit-ray-backend to submit a new job, that job can run indefinitely with no timeout. We need a way to have a configurable timeout value and cancel the job after exceeding the time.

After having a quick discussion with Dean, this can probably be done simply by changing the ray.get() to a ray.wait() (which should've been the case anyway). Then poll for status and kill the job after a certain elapsed time.
