Go: What a central PGO server could look like

Hi! Intrigued by the recent publicity of profile-guided optimisations in Go 1.20 and 1.21. Thought it'd be cool to build something simple that could be used to streamline go service pgo initiatives.

Presented is just an idea; it is intentionally rudimentary. Will give a go measuring this in an actual environment and collecting some metrics.

Any feedback on this topic would be highly appreciated. Thanks.
