Add support for CloudFront limits

[TagadaPoe]

Feature Request

Support for the limits of the CloudFront service.

Feature Description

I am especially interested in checking the usage of the following Quotas:

• Data transfer rate per distribution
• Requests per second per distribution
• Distributions per AWS account
• Cache behaviors per distribution
• Public keys in a single key group
• Key groups associated with a single cache behavior
• Key groups per AWS account
• Distributions associated with a single key group

Note: the CloudFront service, and the related Quotas are available only in the "us-east-1" region, this is a global service.

Unfortunatly, the applied Quotas are not available through the Quotas API.

Testing Assistance

I will be able to assist in testing pre-release code for the feature.

[TagadaPoe]

I am currently working on a PR to implement some CloudFront limit checks.

[jantman]

A fix for this has been released in 12.0.0, which is now live on PyPI and Docker Hub. Thank you so much!
