Feature Request: Add ImagePullSecrets to a service account

[Vad1mo]

Besides creating secrets, the option to add imagePullSecrets to a service account would be a pleasant addition.

Example:

kind: HarborSync
metadata:
  name: my-project
spec:
  type: Regex
  name: "my-project" # <--- specify harbor project
  robotAccountSuffix: "k8s-sync-robot" # <--- should be unique per kind: HarborSync
  mapping:
  - type: Translate
    namespace: "team-a" # <--- target namespace
    secret: "my-project-pull-token" # <--- target secret name
  - type: Translate
    namespace: "team-b"
    secret: "my-project-pull-token"
    serviceaccount: default # <--- add the imagePullSecret to the service account 

We proxy all images and use external Helm Files the might refer to Docker Hub. ImagePullSecret on ServiceAccounts one doesn't need to change the deployment.
