The rolling restart of a Deployment or StatefulSet removes the annotations from spec.template.metadata.

[jfreese]

Describe the bug

The error cased by https://github.com/fabric8io/kubernetes-client/pull/6723/commits

The patch, that is defined in io.fabric8.kubernetes.client.dsl.internal.apps.v1.RollingUpdater.requestPayLoadForRolloutRestart() replaces the hole annotations map found by /spec/template/metadata/annotations and sets the kubectl.kubernetes.io/restartedAt annotation. The patch should merge the annotations map instead.

Fabric8 Kubernetes Client version

Steps to reproduce

1. Create deployment

apiVersion: apps/v1
kind: Deployment
metadata:
  name: test
spec:
  template:
    metadata:
      annotations:
        checksum/event: 8881e757542d422d91cb41b68ff8a0ef60d6cdf22f665b68025d4762575ffb48

2. Run client.apps().deployments().inNamespace("my-namespace").withName("test").rolling().restart()
3. Get Deployment: annotation checksum/event is removed from deployment.

Expected behavior

1. Create deployment

apiVersion: apps/v1
kind: Deployment
metadata:
  name: test
spec:
  template:
    metadata:
      annotations:
        checksum/event: 8881e757542d422d91cb41b68ff8a0ef60d6cdf22f665b68025d4762575ffb48
