Improving SLURM based notebooks and scripts

• add printing of python path for SLURM notebooks since the metadata kernel name is not necessarily the kernel that was used to run the notebook via papermill
• slurm scripts now uses named option to pass arguments
• slurm scripts now correctly specify the kernel name for papermill
• slurm scripts now convert string to int or float, removing the need to convert them in the notebook
• if the kernel is not defined, slurm scripts will try to define one based on the proposal number
