Denton Gentry be9914f714 cmd/sniproxy: move default debug-port away from 8080.
Port 8080 is routinely used for HTTP services, make it easier to
use --forwards=tcp/8080/... by moving the metrics port out of the
way.

Denton Gentry 24d41e4ae7 cmd/sniproxy: add port forwarding and prometheus metrics
1. Add TCP port forwarding.
   For example: ./sniproxy -forwards=tcp/22/github.com
   will forward SSH to github.

   % ssh -i ~/.ssh/id_ecdsa.pem -T git@github.com
   Hi GitHubUser! You've successfully authenticated, but GitHub does not
   provide shell access.

   % ssh -i ~/.ssh/id_ecdsa.pem -T git@100.65.x.y
   Hi GitHubUser! You've successfully authenticated, but GitHub does not
   provide shell access.

2. Additionally export clientmetrics as prometheus metrics for local
   scraping over the tailnet: http://sniproxy-hostname:8080/debug/varz
