This patchset adds missing policy actions to the policy.json
file for several reasons:
1) It signals to operators all the policy actions that are
enforced in the system. With the governance spec [0]
urging projects toward policy in code documentation,
it makes sense to document all policy actions in the
policy.json as Neutron doesn't have policy in code.
2) It is consistent with Neutron's policy enforcement
documentation [1]:
"For each attribute which has been explicitly specified in the
request create a rule matching policy names in the form
<operation>_<resource>:<attribute> rule"
So it makes sense to capture each policy that is enforced,
including all those with these special attributes.
3) Why include "update_router:external_gateway_info" but not
"create_router:external_gateway_info"? This is inconsistent.
4) It makes it difficult to validate Neutron's policy via Patrole
if the policies aren't contained in the policy.json -- how else
is it possible to determine which policies to expect if they
aren't documented anywhere?
