The Maestro documentation states that custom arguments args can be passed to the batch block such that the user can specify additional scheduler writing steps that are not default keys in Maestro. The docs state that args is passed as a dictionary in the yaml file. For example:

batch:
    type: lsf
    host: lassen
    bank: flask
    queue: pdebug
    args:
      alloc_flags: ipisolate

which should result in writing a bash script like so:

#BSUB -nnodes 1
#BSUB -q pdebug
#BSUB -G flask
#BSUB -W 00:30
#BSUB -alloc_flags ipisolate

However, when in reality #BSUB -alloc_flags ipisolate does not show up in the file. My guess is that the code that should be writing this would be located in maestrowf/interfaces/script/lsfscriptadapter.py, but as far as I can tell, no code related to args is present.
