Improves routing for dynamic routes

[ofhouse]

This PR adds the following:

• [Terraform] Destroy created S3 buckets on stack deletion
• [Proxy] Better support for dynamic routes like /test/[id]/[something]
• local e2e tests for test/fixtures/*

ToDo

• Use Proxy as Lambda (With CloudFront events) in e2e tests
• Use API-Gateway in AWS SAM for e2e tests
• Original path is not passed into the lambda
  Possible Solution here would be to change the path in API Gateway to support proxy events:
  1. Change API Gateway path from /__NEXT_PAGE_LAMBDA_0 -> /__NEXT_PAGE_LAMBDA_0/{+proxy}
  2. Then we pass the original path from Cloudfront as proxy argument dealmore.de/abc/def/ghi -> __NEXT_PAGE_LAMBDA_0/abc/def/ghi
  3. We then remove the Lambda path /__NEXT_PAGE_LAMBDA_0 from the Path -> /abc/def/ghi
• Make e2e test run with static file routes
• Support for Fallback routes? -> Deferred Add support for fallbacks #19
