Context:
Currently there is no logic in the engine data generator that purposely creates canceled flow/activity node instances. As we have a filtering feature for this state since OPT-2428 we should extend the generator as well to contain a process that contains (maybe randomly) canceled flow node instances.

AT:

• the data generation creates canceled activity/flow node instances for at least one process (that may preferably indicate by name this behavior, so we can easily identify it in the process selecxtion)
