This introduces a polymorphic scale client capable of operating against scale subresources which return different group-versions of Scale. The scale subresources may be in group-versions different than the scale itself, so that we no longer need a copy of every scalable resource in the extensions API group. To discovery which Scale group-versions go to which subresources, discovery is used. The scale client maintains its own internal versions and conversions to several external versions, with a "hub" version that's a copy of the autoscaling internal version. It currently supports the following group-versions for Scale subresources: - extensions/v1beta1.Scale - autoscaling/v1.Scale Kubernetes-commit: d61a2d90372c301dd11088df8941acf2bb01c38c
