Support for 'autoscaling/v1' version in Scale object

[mzeljkovic]

There's a slight difference in Scale object in autoscaling/v1 version where the selector field is a string instead of an object.
This results in ValidationRejection when you attempt to do any of the following calls:
skuber.getScale[ReplicaSet]("myReplicaSet")
skuber.getScale[StatefulSet]("myStatefulSet")

e => JsError(List((/status/selector,List(JsonValidationError(List(error.expected.jsobject),WrappedArray())))))

akka.http.scaladsl.server.RejectionError: ValidationRejection({"obj.status.selector":[{"msg":["error.expected.jsobject"],"args":[]}]},Some(skuber.json.PlayJsonSupportForAkkaHttp$PlayJsonError: {"obj.status.selector":[{"msg":["error.expected.jsobject"],"args":[]}]}))

Hey Skuber Team.
I have the same issue, but with Deployment.
Is there any plan or workaround available to make it work?
