1. metrics: add os-level cpu stats to pd …

   Pulls in the `metrics-process` crate [0] to bolt on CPU usage and other OS-level info
   to the metrics emitted by pd. Doing so will support a better first-run
   experience for node operators who lack a comprehensive pre-existing setup for monitoring node health,
   so they can get a sense of how much load pd is under.
   
   Adds a cursory first-pass on a new dashboard, but will need to follow up
   on that once the new metrics actually land on hosts that are receiving
   load. Also included a reference to metrics addd in #4581, as a treat.

2. fix: metrics dev-env for linux …

   Fixes a hardcoded path in the compose setup for local metrics. Updates
   the docs, as well, to clarify that the first-run experience via docker
   compose is only relevant for Linux hosts, due to use of host-networking.
   Will work on a macos-compatible dev env later, but for now focusing on
   making sure what's in the repo is clear and runnable for actual testnet
   node operators, which means Linux boxes.
   
   Closes #4565.
