feat: Add anonymized telemetry to report product usage (#2273)

* feat: Add anonymized telemetry to report product usage

This adds a background service to report telemetry to a Coder
server for usage data. There will be realtime event data sent
in the future, but for now usage will report on a CRON.

* Fix flake and requested changes

* Add reporting options for setup

* Add reporting for workspaces

* Add resources as they are reported

* Track API key usage

* Ensure telemetry is tracked prior to exit
