this lives on frontend, but it's not specific to frontend, right? I.e., we show all requests from all services here?

Correct. The frontend dashboard includes a few different metrics like this (that are not specific to any particular microservice), so I thought this new one was similar.

This PR adds a Prometheus metric that tracks the rate that Sourcegraph issues HTTP request that target external hosts (e.g. github.com, gitlab.com, etc.)
For every HTTP request, the metric tracks the hostname, HTTP method, and response code.
I have also added a new "External HTTP Request Rate" section the frontend Grafana dasboard that plots this metric. See the example screenshot below.
