	KubernetesClientSet() (*kubernetes.Clientset, error)

	// Returns a RESTClient for accessing Kubernetes resources or an error.
	RESTClient() (*restclient.RESTClient, error)

	// NewBuilder returns an object that assists in loading objects from both disk and the server
	// and which implements the common patterns for CLI interactions with generic resources.
	NewBuilder() *resource.Builder

	// Returns a RESTClient for working with the specified RESTMapping or an error. This is intended
	// for working with arbitrary resources and is not guaranteed to point to a Kubernetes APIServer.
	ClientForMapping(mapping *meta.RESTMapping) (resource.RESTClient, error)
	// Returns a RESTClient for working with Unstructured objects.
	UnstructuredClientForMapping(mapping *meta.RESTMapping) (resource.RESTClient, error)

	// Returns a schema that can validate objects stored on disk.

	// OpenAPISchema returns the schema openapi schema definition
	OpenAPISchema() (openapi.Resources, error)

Factory provides abstractions that allow the Kubectl command to be extended across multiple types of resources and different API sets. The rings are here for a reason. In order for composers to be able to provide alternative factory implementations they need to provide low level pieces of *certain* functions so that when the factory calls back into itself it uses the custom version of the function. Rather than try to enumerate everything that someone would want to override we split the factory into rings, where each ring can depend on methods in an earlier ring, but cannot depend upon peer methods in its own ring. TODO: make the functions interfaces TODO: pass the various interfaces on the factory directly into the command constructors (so the commands are decoupled from the factory).
