RG changes seem to apply but don't propagate to resources

[candonov]

Steps to reproduce:
Create a ResourceGroup with deployment, set imagePullPolicy to IfNotPresent:

          spec:
            serviceAccountName: ${spec.name}
            containers:
            - name: ${spec.name}
              image: ${spec.image}
              imagePullPolicy: IfNotPresent
              ports:
              - containerPort: ${spec.port}

Change the imagePullPolicy to Always and re-apply:

          spec:
            serviceAccountName: ${spec.name}
            containers:
            - name: ${spec.name}
              image: ${spec.image}
              imagePullPolicy: Always
              ports:
              - containerPort: ${spec.port}

Validate that the RG was updated:

❯ k get rg application.x.symphony.k8s.aws -o yaml| grep imagePullPolicy
              imagePullPolicy: Always

Create an instance and check the deployment:

❯ k get deployments.ap s3demo -o yaml |grep imagePull
        imagePullPolicy: IfNotPresent

Add a service account to the resource group:

  - name: serviceaccount
    definition:
      apiVersion: v1
      kind: ServiceAccount
      metadata:
        name: ${spec.name}
        namespace: ${spec.namespace}

Reapply the RG, create another instance, the new instance doesn't create a serviceaccount.
