Jetpack product discussion

Does this pull request change what data or activity we track or use?

Testing instructions:

• You'll need a dev blog for this

jetpack build --production plugins/jetpack
jetpack rsync jetpack [email protected]:/srv/htdocs/wp-content/plugins/jetpack

You can add Personal, Premium, and Business plans and ensure nothing changes. Given that the feature gating on Jetpack is not really functional for anything other than Jetpack Forms, it's not easy to test.

You can:

• Add a Jetpack form that has a file upload
• Bu following the sticker approach in 197503-ghe-Automattic/wpcom, you can see that the file upload becomes gated behind an upsell

All the other features will need subsequent upsells to become hidden behind upsells on Atomic.
