Breaks up the ARC documentation into several smaller articles. `@vijay-train` and `@martin389` put together the plan for this update, and I've just followed it here. In these updates: - The README has been updated to include more general project information, and link to each new article. - The `detailed-docs.md` file has been broken up into multiple articles, and then deleted. - The Actions Runner Controller Overview doc has been renamed to `about-arc.md`. Any edits to content beyond generally renaming headers or fixing typos is out of scope for this PR, but will be made in the future.

Monitoring and troubleshooting
Metrics
The controller also exposes Prometheus metrics on a /metrics endpoint. By default this is on port 8443 behind an RBAC proxy.
If needed, the proxy can be disabled in the values.yml file:
metrics:
serviceAnnotations: {}
serviceMonitor: false
serviceMonitorLabels: {}
+ port: 8080
proxy:
+ enabled: false
If Prometheus is available inside the cluster, then add some podAnnotations to begin scraping the metrics:
podAnnotations:
+ prometheus.io/scrape: "true"
+ prometheus.io/path: /metrics
+ prometheus.io/port: "8080"
