Quota Page: Show EC2 Instance Type availability per Region+AZ

[neilramsay]

I want to display the number of Availability Zones that an Instance Type is available in.

This gives an operator an indication of how much capacity is likely to be available, and therefore the latency between a Spot Request and it's fulfillment.

This changes:

• Installer bin/index.js to include instance types, and AZ availability per Region in the familyRegions variable
• Update usage of familyRegions variable in Pricing Service, New Campaign, and Quota pages.
• Quota page includes new divs to show colour coded "bagdes" showing the availability.
