1) get the transformation IDs of jobs that are older than 1 year
2) find the status of those transformations. Those "Cleaned" and "Archived" will be
cleaned and archived (again)
Why doing this here? Basically, it's a race:
1) the production manager submits a transformation
2) the TransformationAgent, and a bit later the WorkflowTaskAgent, put such transformation in their internal queue,
so eventually during their (long-ish) cycle they'll work on it.
3) 1 minute after creating the transformation, the production manager cleans it (by hand, for whatever reason).
So, the status is changed to "Cleaning"
4) the TransformationCleaningAgent cleans what has been created (maybe, nothing),
then sets the transformation status to "Cleaned" or "Archived"
5) a bit later the TransformationAgent, and later the WorkflowTaskAgent, kick in,
creating tasks and jobs for a production that's effectively cleaned (but these 2 agents don't know yet).
Of course, one could make one final check in TransformationAgent or WorkflowTaskAgent,
but these 2 agents are already doing a lot of stuff, and are pretty heavy.
So, we should just clean from time to time.
What I added here is done only when the agent finalize, and it's quite light-ish operation anyway.
