Various controllers read from multiple clusters.

This is rooted in the Multicluster Secret controller, which reads `kubeconfig` files (stored as `Secrets`), and creating Kubernetes clients for each. The controller allows registering handlers which can process Add/Update/Delete of clusters.

This has two implementations:
* The Credentials controller is responsible for reading TLS certificates, stored as Secrets.
