Policy will support a new category of policies, "external policies", such that the enforcement point of the policy is external to ONAP. Metadata will indicate the enforcement point target type of an "external policy" type.
Policy will maintain a repository of policy instances of external policies, each being assigned a unique id. Associated with each policy instance will be a "state":
- Pending: The policy instance has been created but has not yet been propagated to any enforcement point instances.
- In Effect: The policy instance has been propagated to at least one enforcement point instance.
- Pending Cancel: The policy instance has been canceled, but the cancellation has not yet been propagated to the enforcement point instances.
- Historic: The policy instance cancellation has been propagated to all enforcement point instance.
Policy will be able to bulk send all Pending and In Effect policies to SDN-R
