Code Issues Proposed changes

Use an ordinal server naming pattern 

As discussed during the "Launch Node, Ansible and Puppet" summit
session in Austin, we're making things unnecessarily hard on
ourselves by insisting on having multiple servers in our inventory
with the same name. In order to make server addition and replacement
automation simpler, start using an ordinal suffix on server short
names to differentiate them (we can still easily rely on DNS for
their non-numbered convenience names).

@ -120,8 +120,11 @@ To create a new server, do the following:
* Add a file in :file:`modules/openstack_project/manifests/` that defines a
class which specifies the configuration of the server.
* Add a node entry in :file:`manifests/site.pp` for the server that uses that
class.
* Add a node pattern entry in :file:`manifests/site.pp` for the server
that uses that class. Make sure it supports an ordinal naming pattern
(e.g., fooserver01.openstack.org not just fooserver.openstack.org, even
if you're replacing an existing server) and that another server with the
same does not already exist in the ansible inventory.
* If your server needs private information such as passwords, use
hiera calls in the site manifest, and ask an infra-core team member
