Pre and post rollout hooks #4471
Description
Summary
I would like Argo Rollouts to trigger specified kubernetes job before rollout starts and after rollout finishes. It could be similar to analysis job but it should provide information about the status (success, failed) of the job also.
For canary it can be worked around right now by using canary job step, but this feels like a hack.
This would also provide a lot more flexible way of sending notifications/events...
Use Cases
I want to use post rollout hook to trigger rollout in next production environments in staggered manner. Basically when rollout in region-a finishes it will trigger rollout in region-b and so on ... this way only one region is being upgraded at a time and when region succeeds next one is started.
