Verify operation in keystone

[Francesco Foresta]

- [X] This doc is inaccurate in this way:

In point 2, it is suggested to run

  openstack --os-auth-url http://controller:35357/v3 \
  --os-project-domain-name Default --os-user-domain-name Default \
  --os-project-name admin --os-username admin token issue

However, the endpoint has been configured on port 5000 previously.
This is a sort of garbage inherited from previous OpenStack versions where "keystone needed to be run on two separate ports to accomodate the Identity v2 API which ran a separate admin-only service commonly on port 35357."

- [X] I have a fix to the document that I can paste below including example:

Replace the previous command with

  openstack --os-auth-url http://controller:5000/v3 \
  --os-project-domain-name Default --os-user-domain-name Default \
  --os-project-name admin --os-username admin token issue

Take care!
Francesco
