[Cloud Deploy] Using profiles with multi target deploys

[roopakv]

Google Cloud Deploy supports multi targets by creating a child target. However the profiles configuration is a part of the pipeline config so during rendering the profiles go missing.

e.g. let us assume I have a web-server and a jobs-server that I want to deploy in parallel. The following config sort of works

apiVersion: deploy.cloud.google.com/v1
kind: DeliveryPipeline
metadata:
  name: parallel-deploy-example
description: Parallel deploy Example
serialPipeline:
  stages:
    - targetId: all-servers
      profiles: [profile1, profile2]
---
apiVersion: deploy.cloud.google.com/v1
kind: Target
metadata:
  name: all-servers
description: Deploy all servers
multiTarget:
  targetIds:
    - web-server
    - jobs-server
---
apiVersion: deploy.cloud.google.com/v1
kind: Target
metadata:
  name: web-server
  labels:
    service-type: web server
description: staging web us-central1
run:
  location: projects/something/locations/us-central1
---
apiVersion: deploy.cloud.google.com/v1
kind: Target
metadata:
  name: jobs-server
  labels:
    service-type: jobs
description: jobs server
run:
  location: projects/something/locations/us-central1

Now While I can pass profile1 profile2 to both servers I can't pass a profile specifically for web-server and a different profile for jobs server.

However when doing it serially since each step has a profiles array I can give them their own profile.

Is there some secret config I am missing or is this a limitation I have to live with.
