-- Deletes the specified policy.
--
-- A policy cannot be deleted if:
--
-- - it has non-default versions
--
-- - it is attached to any certificate
--
-- To delete a policy:
--
-- - First delete all the non-default versions of the policy using the
-- DeletePolicyVersion API.
--
-- - Detach it from any certificate using the DetachPrincipalPolicy API.
--
-- When a policy is deleted, its default version is deleted with it.
