Get disk space usage and throw an error for low disk space (#693)

This leverages `setup-miniconda` to print out the disk usage and throw an error when the available space is less than a certain amount (3GB)

This PR doesn't attempt to clean up disk space pending some discussion on pytorch/pytorch#84841
