ENH: Fetch container scheduler logs when it fails to start and return to client

Would it be possible for the gateway server to fetch the scheduler startup logs and return them to the client, generally speaking? In my specific case, it was a little challenging to figure out why my scheduler was failing to start. Eventually I was able to reason that I should be tailing the pod logs to see why it was failing to start and that showed me that the dask_gateway wasn't actually installed in my docker image that I was trying to use (oops). But without admin-level access to the k8s cluster, I wouldn't be able to know that.
