I'll add an additional test for updating nested relationships, but the changes can be reviewed.
However, I'm considering a separate PR for discussion based on this one, with only TaskConfig and TaskActivity, that can replace the classes added in this PR as the following:

• Campaign -> TaskConfig[xxx__campaign]
• TaskConfig -> TaskConfig[xxx__config]
• TaskConfigGeneration -> TaskActivity[xxx__config_generation]
• TaskExecution -> TaskActivity[xxx__execution]

where:

task_config_type (enum):

• circuit_simulation__campaign
• circuit_simulation__config
  ...

task_activity_type (enum):

• circuit_simulation__config_generation
• circuit_simulation__execution
  ...

This would allow to define workflows of task_config with more than 2 activities.
