Golang proactively prints this error `http: proxy error: context canceled` when a request arrived to the current deployment and redirected to another deployment in a federated setup. Since this error can confuse users, this commit will just hide it.
- Supports centralized `config.json` - Supports centralized `bucket` service records for client lookups - implement a new proxy forwarder
