// Package policy describes a generic interface for retrieving policies.
// Different implementations are possible for environments such as Kubernetes,
// Mesos or other custom environments. An implementation has to provide
// a method for retrieving policy based on the metadata associated with the container
// and deleting the policy when the container dies. It is up to the implementation
// to decide how to generate the policy.
// The package also defines the basic data structure for communicating policy
// information. The implementations are responsible for providing all the necessary
// data.
