Reason

the apigateway container complains about an error:

==> /var/log/api-gateway/management.log <==
2020/07/01 03:15:21 [error] 56#0: *65 lua entry thread aborted: runtime error: /etc/api-gateway/scripts/lua/routing.lua:250: bad argument #1 to 'pairs' (table expected, got nil)

and after look through codes and debugging, it seems that in second and subsequent api creation, the method scripts/lua/management/lib/swagger.lua#parseSwagger which should call method scripts/lua/management/lib/swagger.lua#parsePolicies but actually it's called scripts/lua/routing.lua#parsePolicies

and this error also lead to some system tests failed:

although I didn't know the real reason why there is conflict, but seems it is imported by openrestry upgrade: #374
