ExternalGroup reference

Coming in enterprise-2.16

BEL provides external workload management for Linkerd in the form of a Kubernetes controller and a proxy harness daemon. The controller runs on the cluster and allows for automated ExternalWorkload lifecycle and configuration management. This is achieved with the use of an ExternalGroup resource which defines a template for creating ExternalWorkload resources.
