Merge task schema is missing completion option

[eedokl]

Problem Description

Currently we cannot configure completion condition behavior of merge task, it will always default to tasksuccess.
However, in my use case it can happen that the merge task fails at some point but I still want to upload its output it gave so far, so I would like to set it to taskcompletion instead.
I tried to just extend the jobs schema to also allow condition and this seems to work fine (probably since a merge task is also "just" a task which just depends on all other tasks.
