slurm: environment improvements #371
Description
The current slurm scheduler specifies the working directory via the image field of the Role. This doesn't match how any of the other schedulers work since local_cwd has been switched to use the current working directory. We should update the slurm scheduler to be more inline with the other schedulers.
- make slurm_scheduler use
cwdinstead of the image path
The current behavior was around the assumption that users would specify the image as part of the args but that doesn't match how users use TorchX today
slurm also automatically inherits the local conda/virtualenv so not much needs to be done here
would be nice to also support logs though
