Steps to reproduce:
1. Set a jobload in an encoding profile as documented at https://docs.opencast.org/r/3.x/admin/configuration/load/#step-3-setting-the-load-values-for-encoding-profiles for example:
profile.presenter-mp4-parallel.http.jobload = 3.0
2. Create a workflow that uses the composer operation with the profile
The job load for the operation is the default 1.0 rather than the jobload specified in the profile
The operation's job load should be set from the profile's job load.
