* Allow the che-operator to install the Kubernetes Image Puller operator and configure a KubernetesImagePuller CR in the same namespace that che is installed in.
Adds a new field to the CheCluster CR, imagePuller, that will install the operator and create a CR if enabled. If disabled, it will uninstall and remove the image puller artifacts.
