Get access to client objects

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

	- Kubernetes resources
	- Pipelines resources (https://github.com/tektoncd/pipeline)
	- Triggers resources (https://github.com/tektoncd/triggers)
