After this it should be possible to build a working `packager` application from the `cmake` branch. Some further logging improvements may be needed to get full parity with the `main` branch in terms of ability to do verbose debug logging, but other than that everything is expected to work.
Moved all code dealing with jobs into its own class so that the
packager code does not need to worry about initializing, running,
or stopping jobs.
