[Feature] Add Annotations

[johandry]

Is your feature request related to a problem? Please describe. This is a nice to have feature, it's not a problem yet

Describe the solution you'd like All the objects modified by klient should have an specific annotation. Optionally, we can allow the developer to set it's own annotation.

Describe alternatives you've considered As an alternative the annotation could be included in the content or file to apply.

Proposal Before create or update the object call:

err := util.CreateOrUpdateAnnotation(annotation, info.Object, scheme.DefaultJSONEncoder())

to append this annotation to the object, this should be in the func called by r.Visit(info) such as create() and patch()

Additional context It's in kubectl but it does append the annotation provided by the user
