TMPDIR is set to mcp by default on outline wrapper. It should be set on the outline config file

Describe the enhancement When launching a job using pyoutline, users are facing the following error:

mkdir: cannot create directory ‘/mcp’: Permission denied
Bad : modifier in $ ( ).

The wrapper script is hardcoded to /mcp which is not a common directory on people's environments. Ideally this should be configured and documented on the outiline.cfg file.
