Adding category/metadata to each role

(moved from comment in review of #2)

It would be really good to have some high level information about each role captured somewhere. I think about who is going to use this and think that it would be desirable to have the following captured for each JD (ideally in a searchable fashion):

• Formal Job title
• Organization
• Organization type
• Department
• Category
• Full time/part time
• Domain

So for example:

• Research Software Engineer, Senior RSE, Scientific Programmer, Computer Scientist
• Princeton University, ORNL,
• University, National Lab, Industry
• Research Computing, Molecular Biology, Computer Science,
• IT, Research
• Full time
• Molecular Biology, Economics, HPC, etc

If this gets to be a big enough database having the ability to sift through different roles based on keywords in these categories would be great.

I think this could all be added later.

And another important piece of info:

• Date posted/last active
