Remco Ros 7c12b58bb5 fix: refactor dns to handle tcp connections: (#3083) ...

* fix: refactor dns to handle tcp connections:
- do not use long-lived tcp connections to upstream dns servers
- when incoming request is over tcp, force a tcp lookup instead of udp

this solves cases where large dns records were not being resolved due to udp->tcp switch-over.

* use forwarding resolver for fallback
