Description
Finagle can (optionally) record per-endpoint statistics. We should add a router-client-level configuration parameter to enable recording of these metrics, and integrate them into the admin UI.
These metrics should be disabled by default because they can be quite costly performance-wise (esp for large clusters), but it's a great feature to have when individual backends matter. In larger clusters, tracing is probably a better way to attack this, anyway.

Research direction
Start by locating the router-client-level configuration and the admin UI entry point for metrics. Check how Finagle per-endpoint statistics can be enabled, then verify that recording remains disabled by default and that enabled metrics appear in the admin interface; no specific files or tests are named.
