Support Argo Rollouts resources #217

Hi,

Argo Rollouts is a Kubernetes controller and set of CRDs which provide advanced deployment capabilities such as blue-green, canary, canary analysis, experimentation, and progressive delivery features to Kubernetes.

Is it possible to support the Rollout CRD so that kubedog will output the events from the resource?

example:

❯ kubectl describe -n demo-chart-ru-test6 ro demo-chart
Name:         demo-chart
Namespace:    demo-chart-ru-test6
Labels:       app.kubernetes.io/managed-by=Helm

              meta.helm.sh/release-namespace: demo-chart-ru-test6
              project.werf.io/env: ru-test6
              project.werf.io/name: demo-chart

@rgeraskin Hi! It is totally possible to implement such tracker. Support for flagger Canary resource kind have been added recently #218. Argo Rollouts can be added in a similar way.

We welcome PRs adding even some very basic version of such tracker (which could just hang until Rollout is ready, without underhood details).
