Made a small fix to the documentation - replacing
the current auth_url port number 35357, in the
configuration section of the [keystone_authtoken],
with 5000.
This was based on an online conversation with Colleen;
with the removal of the v2 API from keystone the project
now recommends use of port 5000 instead of the previous one.
