Customer ports by rack / switch view, not just by site.

[listerr]

The admin dashboard page of IXP Manager has port count tables:

• Customers by Location
• Customer Ports by Location

As some sites have more than one rack, It would be really useful for us if we could have a "ports by rack" table, or if the existing location tables had clickable rows to expand to counts in each rack.

Here's a model I did by extracting the info out of the DB and using a pivot table, breaks it down
by cabinet and by switch, since some of our locations (THN, HEX) have more than one cabinet - an old PoP and a new PoP, in different places in the site. In some sites, it's also useful to see the spread of ports across switches.
