Disabling routing requests through `http-router`

Whilst we’re passing through the majority of the traffic to our existing gitlab.com infrastructure we have the ability to disable routing requests through to the http-router. If we’re seeing issues at the http-router layer we can disable the routing through this layer temporarily.

Steps:

1. Remove the CloudFlare Worker routes (one of the below options)
   1. Remove the the cloudflare-workers.tf file for the affected environment
   2. Set the count for the Terraform resources for affected routes to 0
2. Create an MR and get approval
3. Apply with atlantis apply
