v0.63.0

Add support for a custom cache policy @dmattia (#140)

what

• AWS has a relatively new CloudFront feature named Cache Policies: https://aws.amazon.com/blogs/networking-and-content-delivery/amazon-cloudfront-announces-cache-and-origin-request-policies/
• This adds support for the default cache to set an explicit cache policy
• This also sets restrictions on not allowing some other params to be set if the cache policy is specified, as is consistent with the AWS Console's wizard when creating a distribution.

This module could also create a cache policy itself if desired, I would gladly make that change.

Note: I support a module for creating cache policies: https://registry.terraform.io/modules/transcend-io/cache-policy/aws/latest

why

• Cache Policies are the easiest (only?) way to add brotli compression in CloudFront
