Install and configure controller node in Neutron

[Joe Lilly]

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:

The Neutron install doc for QUEENS points to an incorrect port for keystone. 'auth_url = http://controller:35357' should be 'auth_url = http://controller:5000' as that's what the install doc for keystone uses.

Keystone install guide reference: https://docs.openstack.org/keystone/queens/install/keystone-install-ubuntu.html#install-and-configure-components

- [ ] This is a doc addition request.
- [ ] I have a fix to the document that I can paste below including example: input and output.
