Get access to client objects

To initialize client objects you can use the setup function. It returns a clients struct
that contains initialized clients for accessing:

	- Kubernetes objects
	- Pipelines (https://github.com/tektoncd/pipeline#pipeline)

For example, to create a Pipeline

	_, err = clients.V1beta1PipelineClient.Pipelines.Create(test.Pipeline(namespaceName, pipelineName))

And you can use the client to clean up resources created by your test

	func tearDown(clients *test.Clients) {
	    if clients != nil {
	        clients.Delete([]string{routeName}, []string{configName})
	    }
	}
