Cannot set job load for individual composer jobs


While Job Load is promising to help to better load worker nodes, it missed to provide the facility set use this for some important jobs.

In particular, the image extraction jobs would highly benefit from the Job load mechanism when a large number of images is being extracted (e.g. segment previews, extraction previews at multiple positions in multiple qualities).

Unfortunately, it is not possible to set job weights for individual operations offered by the composer which implies that encode has the same weight as image, for example.

Since Job Load is a new feature just being introduced in Opencast 2.2 and this change is quite trivial, I think it makes sense to directly include it in 2.2 to avoid people having to adjust their configuration after having introduced Job Load already.

Oh, just read the docs and found: Step 3: Setting the load values for encoding profiles

This solves the problem.
