Plugin request: send event data to a different PostHog instance

[macobo]

Is your feature request related to a problem?

When doing "release testing" one thing we have constantly struggled with is testing how the changes perform on a larger self-hosted instance.

Let's fix that!

Describe the solution you'd like

Create a plugin which submits all events for our team to a postgres-based deployment. If the scale is still too small, add functionality to amplify the writes (e.g. 3 events for every 1 ingested).

Describe alternatives you've considered

Make a really really popular other product.

Additional context

Thank you for your feature request – we love each and every one!
