-- 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 action to delete all
-- non-default versions of the policy; use the DetachPolicy action to
-- detach the policy from any certificate; and then use the DeletePolicy
-- action to delete the policy.
--
-- When a policy is deleted using DeletePolicy, its default version is
-- deleted with it.
--
-- Because of the distributed nature of Amazon Web Services, it can take up
-- to five minutes after a policy is detached before it\'s ready to be
-- deleted.
--
-- Requires permission to access the
-- <https://docs.aws.amazon.com/service-authorization/latest/reference/list_awsiot.html#awsiot-actions-as-permissions DeletePolicy>
-- action.
