KubeClient v2.2.0

Changes

• Introduce KubeResultV1 and use it for delete operations (#55)

Breaking Changes

• Delete operations on Kubernetes resource clients now return KubeResourceResultV1<TResource> because, depending on the specified (or default) delete-propagation policy, those operations could return either the resource or a StatusV1. This change is source-compatible (just not binary-compatible).
• Instead of taking a DeletePropagationPolicy with a default of Foreground, delete operations on Kubernetes resource clients now take a DeletePropagationPolicy? with a default of null (#55).
