[Rdo-list] RDO repo location change

[Perry Myers]

The RDO repos are located here:

http://repos.fedorapeople.org/repos/openstack/

With a redirect of the form:

http://rdo.fedorapeople.org -> http://repos.fedorapeople.org/repos

Meaning that most of the wiki pages have links like this:

http://rdo.fedorapeople.org/openstack/openstack-grizzly/rdo-release-grizzly.rpm

Made more sense to have rdo.fedorapeople.org redirect directly to the
openstack subdirectory, so the above urls were corrected to be like:

http://rdo.fedorapeople.org/openstack-grizzly/rdo-release-grizzly.rpm

As http://rdo.fedorapeople.org now redirects to:
http://repos.fedorapeople.org/repos/openstack

Minor change, and I corrected the Quickstart and Neutron Quickstart
pages, but there may be other pages that need minor updates, so if you
see a url broken due to this change just fix it :)
