Update infrastructure diagrams with Omnigraffle

A good place to start would be to update and inventory the Drupal.org infrastructure so everyone knows what we have and how our little virtual machine for the redesign development and staging comes into play.

In this issue from last year, http://drupal.org/node/155850#comment-626523, we updated the hardware diagrams.

A list of hardware is available to D.O. production infrastructure team members here: http://infrastructure.drupal.org/node/36
A backend network map is available to D.O. production infrastructure team members here: http://infrastructure.drupal.org/node/44

If you are interested in updating these diagrams, and you have Omnigraffle, please respond and I'll get all the raw information to you.

Cheers,
Kieran
