// Package application documents patterns for building Controllers to manage specific applications.
//
// An application is a Controller and Resource that together implement the operational logic for an application.
// They are often used to take off-the-shelf OSS applications, and make them Kubernetes native.
//
// A typical application Controller may use builder.ControllerManagedBy() to create a Controller
// for a single API type that manages other objects it creates.
//
// Application Controllers are most useful for stateful applications such as Cassandra, Etcd and MySQL
// which contain operation logic for sharding, backup and restore, upgrade / downgrade, etc.
