make cloud onboarding survey disableable via runtime feature flag (#7407)

## Summary

The survey is causing some friction. It incurs about 5-10% dropoff.
Although that number is actually somewhat slow, the information has
mostly served its purpose for now. We can toggle it freely once this PR
is merged.
