[chef] Possibilities for node_name in Chef client configuration

[Jeff Blaine < >]

The default client.rb setting for node_name is "what Ohai determined to
be the FQDN of the node"

In our environment, this causes a total mess. Due to many factors
outside of our control:

* node['fqdn'] for some nodes is of the form: foo
* node['fqdn'] for some nodes is of the form: foo.DOMAIN
* node['fqdn'] for some nodes is of the form: foo.domain

That's a real party when using knife, let me tell you.

Because of this, we clearly want to normalize our node *object* names.

How does one reference the current node object in client.rb so that I
can effectively do something like:

    def site_normalize
      # stuff
    end

    node_name site_normalize(the_node_fqdn)
