IDE (VSCode/PyCharm) connectivity support?

[elgalu]

Is it being considered to support VSCode and/or PyCharm IDE connectivity to offload local GPU debugging work into a Kubernetes GPU cluster (e.g. Python breakpoints) ?

Currently it's possible to arena submit [job] ... then arena attach JOB ... but the user would need to put some kind of sleep for the submit job not to end.

Also, in order to be able to connect a local IDE, kubectl attach doesn't suffice but would also require arena to transparently forward a SSH port. Is some sort of good UX being considered for such use cases?

If the user prefers to continue working on their local copy within their IDE then a continuously rsync should be kept running that updates the source code remotely in the GPU pod. Right now it seems something like --sync-source=. is not supported, i.e. to sync the files from the current directory in the user's laptop.
