-- Deletes the specified policy.
--
-- A policy cannot be deleted if it has non-default versions or it is
-- attached to any certificate.
--
-- To delete a policy, use the DeletePolicyVersion API to delete all
-- non-default versions of the policy; use the DetachPrincipalPolicy API to
-- detach the policy from any certificate; and then use the DeletePolicy
-- API to delete the policy.
--
-- When a policy is deleted using DeletePolicy, its default version is
-- deleted with it.
