Resource action equivalent to kubectl rollout restart

[jessesuen]

Is your feature request related to a problem? Please describe.

A common feature request is to be able to restart all pods of a deployment. This is basically the new kubectl rollout restart feature in kubectl v1.15:

https://github.com/kubernetes/kubernetes/pull/76062/files

Describe the solution you'd like

A new resource action should be introduced for deployments, "restart", which mimics the behavior of kubectl rollout restart, which essentially sets an timestamp annotation on spec.template.metadata.annotations, kubectl.kubernetes.io/restartedAt to current timestamp.
