// Registry is a list of all of Grafana's core structured kinds, wrapped in a

// with certain Kubernetes controller and apimachinery libraries.
//
// There are two access methods: individually via literal named methods, or as
// a slice returned from All() method.
//
// Prefer the individual named methods for use cases where the particular kind(s)
// that are needed are known to the caller. Prefer All() when performing operations
// generically across all kinds.
