Workflow-monitoring in Unity.py with new jobs DB

[rtapella]

Jobs DB:

• https://github.com/unity-sds/unity-project-management/issues/38

• Will need to update this so it's not jobs-per-process

• Also there may be expanded metadata and/or endpoints

• Filter/sort on server-side using WPS-T calls

[rtapella]

not sure of release for Unity.py support for this

[rtapella]

unlikely to do this if Jobs DB becomes vestigial (e.g. adoption of Airflow for EMS)

[rtapella]

won't do.
