Add support for new service quotas api

[David Dreggors]

Amazon just released Service Quotas which will be the new way to manage service limits (now known as quotas).

The aws cli is updated to add the new request-service-quota-increase (among other service quota functions):

This is a huge benefit to aws cli and api users as create-case did not allow you to manage limit increase requests, historically the only method was to use the console which was cumbersome and allowed to much room for human error in the request. To be able to script and template limit increases now would be very useful.

Here is the request-service-quota-increase command documentation for example:
