This endpoint is only accessible by employees - Create a feature flag called `ebonet_chaos_tests` - When a user hits the `/chaos` endpoint, the feature flag is tested against a random project - If the feature flag is enabled, in 20% of the cases the request will fail, and in 20% of the cases it will add .3s to the processing time. - If the feature flag is disabled, nothing happens Once the feature flag is activated, perform a 1000 requests spaced by 0.5 each. Create a kibana dashboard that shows the comparison of the feature flag, when it is on and when it is off
