Track created jobs

[pennings-tamu]

The researcher should have the option to re-run created jobs.To re-generate we need the following info

• job name
• job location
• generated templates
• uploaded files/directories

Aside from that, it might be useful to store the date the job was run.
If we can assume researcher doesn't delete the original jobs, it will be sufficient to just store the filenames.

This information will be stored under $SCRATCH/drona_composer/jobs. Can either store it in a database type of structure, or just in plain files, either JSON or flat copy
