feat: add experiments and flags product intents

[raquelmsmith]

Problem

If someone is already a posthog user, we want to know if they show intent to start using feature flags and experiments, so they can be part of the activation funnel.

Changes

• Adds product intents for these two things
• Handles the case where someone is an existing already-activated user so those people don't enter our funnel

Does this work well for both Cloud and self-hosted?

Looks fine from the experiments side of things.

Out of curiosity, what does "activated" mean to us?

For experiments, it's launching an experiment (ie adding a start_date). We can change this later if we want.

Oh, I understand how "activated" is measured but what does it actually mean? That the user has "used" the feature?

Great blog post :)

Great blog post :)

My name's on it but it was really 99% lior and ian!

LG! Just the one nit

[havenbarnes]

nit: this feels like it could be a bit brittle, if we changed the prefix for these types of flags. Think it would be too expensive to exclude via a reverse lookup on experiments / surveys? I'm not sure how often this runs.

[raquelmsmith]

Hm, that's probably a better solution. It shouldn't be too expensive because the discrete number of flags / experiments per project is low (ie in the hundreds, not hundreds of thousands).

I'll do that.
