feat(metrics): added metrics and peer_id endpoints

[gurinderu]

Description

Added additional http endpoint for fetching peer_id

Motivation

Right now, people have to dig through nox's logs, which is hard.

Proposed Changes

• metrics_port was renamed to http_port
• added /metrics endpoint
• added /peer_id endpoint

Screenshots (if applicable)

Additional Notes

• peer_id becomes a required parameter for starting the node
• instead of using hyper directly, I have decided to add the axum library. It is much simpler to define endpoints and it uses hyper
• http_config is optional for the ability to disable HTTP API
