Batch additonal args does not work

Nobody has claimed this yet.

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.

Start with the documented batch `args` example and inspect `maestrowf/interfaces/script/lsfscriptadapter.py` for how YAML batch settings become LSF directives. Confirm the generated script includes `#BSUB -alloc_flags ipisolate` when the example configuration is used.
