Expose get timeout to python about ray HOT 2 CLOSED

This could (almost) already be achieved by using

ready_ids, _ = ray.wait(object_ids, timeout=...)
ray.get(ready_ids)

The differences are that

1. This involves a little more code.
2. This involves an extra IPC round trip to the object store.
3. Some of the objects corresponding to the object IDs in ready_ids could in principle be evicted from the object store between between the ray.wait and ray.get call, causing the ray.get call to block for a little while.

Let's hold off on this for now. If there's a need for it, we can certainly add it in.

Right now, the main use case seems to be that you call ray.get in your interpreter and it's taking too long, so you want to do Ctrl-C to exit the get (it would require a lot of foresight to have thought to pass in a timeout ahead of time).
