always copy the context.ctx file

The context.ctx file is copied only if it does not exist. But it could be stale. Why not always copy it?

I have faced weird timing issues when copying ~/.kube/config to $LLMDBENCH_CONTROL_WORK_DIR/environment/context.ctx and that is why I didn't adopt the "always copy" approach. That being said, you are absolutely correct that we cannot afford to have a stored context.ctx which points to the "incorrect" cluster.

Both my team mate and I independently encountered a stale context file yesterday. So it's a real problem. In my case it happened because I switched LLMDBENCH_CONTROL_WORK_DIR to a directory that was previously used as the work dir and contained a stale context file, so you could argue it was my fault. But I think the change avoids the problem all together.

You're right, we need to attempt to minimize it. Please take a look at the state of the code now (after #505 was merged) and let me know if it fixes your issues.
