OS_AUTH_URL is wrong in admin-openrc

[zheng yan]

This bug tracker is for errors with the documentation, use the following as a template and remove or add fields as you see fit. Convert [ ] into [x] to check boxes:

- [x] This doc is inaccurate in this way: In the admin-openrc script, "export OS_AUTH_URL=http://controller:5000/v3" is wrong. The port of admin should be 35357 instead of 5000, in another word, this line should be "export OS_AUTH_URL=http://controller:35357/v3". Moreover, if the port is 5000, in the verify operation, you will have such error "401 Unauthorized: This server could not verify that you are authorized to access the document you requested. Either you supplied the wrong credentials (e.g., bad password), or your browser does not understand how to supply the credentials required. (HTTP 401)".
- [ ] This is a doc addition request.
- [ ] I have a fix to the document that I can paste below including example: input and output.
