feat: support multi stage dockerfile

[jul-dan]

@RemiBonnet I have tested all these cases:

• Create app/job/cronjob with no stage
• Create app/job/cronjob with stage
• Edit app/job/cronjob with from no stage to stage
• Edit app/job/cronjob with from stage to no stage <-- Here I have an issue for cronjobs, it sends a stage whereas I remove the field value. I think it is due to job/cronjobs conflicts.
• Clone app/job/cronjob with no stage
• Clone app/job/cronjob with stage
