 The Remediation Component does the following:
 
 1. Create a Cloudflare Worker and a Worker KV per configured account.
 2. Create a Worker Route(s) per configured zone. Any request matching the route would be handled by the worker.
 3. For every matching incoming request, the worker checks whether it's IP, Country and AS have a decision against. It checks for this in it's KV store. If found it performs the corresponding remediation.
