Currently, when we invoke job.add_args("1 2") it is written to the YAML file as below, but the same is written to the .sh file as 1 2 instead of '1 2'.

```yml

• type: job
  name: ls
  arguments:
• 1 2
• 3 4
  ```

```sh
pegasus-kickstart -n ls -N ID0000001 -o listing.txt -R condorpool -s listing.txt=listing.txt -L .. /bin/ls 1 2 3 4
```

When writing the arguments into the .sh file, they should be shell escaped.
