User-submittable roadmap categories

[corywatilo]

@jamesefhawkins has long-asked for a CDP connector voting board where each item can be voted on from a list. I've pushed back since we can filter by team and we can list potential connectors there, but also realize how it would make sense to have a parent/child relationship here.

Now I have a slightly different use case (user-submittable requests for themes) and I think we can tie both of these together.

Child roadmap items

Basically adding a layer of nesting inside the parent roadmap item

• Votes on a child roll up to votes on the parent
• Cannot vote directly on parent (no parent "Vote" button, only on children)

User-submittable requests

For both CDP connectors and themes, we can have a mode to toggle on user submissions. When enabled, it would add a button to open a form.

Requirements

• Votes would be tied to the user's Strapi record
• We should get a Slack notification upon new submissions
• Probably makes sense to have a moderation queue. I can imagine a world where we either need to clean up submissions (punctuation, formatting) or merge their request with an existing roadmap item.
• The description field wouldn't ever display publicly - it'd just come in handy for when people are requesting obscure services with generic names where we would otherwise have trouble finding the URL.
• Form should have a customizable string for the thing type so it works for CDP connectors, themes, and anything else we might add.
  • Request another [thing name]
  • [Thing name] name
• Confirmation message would say the idea has been submitted and we'll review it/add it soon

Bonus points

Could be cool if a single roadmap item can be embedded. This way, we could

• have a blog post about building themes and embed the requests on the page.
• embed the CDP requests on the CDP small team page
• link to the CDP connector request form from within the app, which would open the side panel and load up a dedicated page without ever having to leave the app
