Do not rely on Sinatra for admin

Currently, mounting a stoplight into your application requires adding Sinatra as a dependency. This is ridiculous if you don't use Sinatra as a web framework. To avoid this confusion, we could:

• Replace Sinatre with Ralis engine (backward compatibility is a must)
  • Pros:
    • There are definitely more Rails apps than Sinatra apps in the wild
    • Rails offers a lot of security and productivity features out of the box.
  • Cons:
    • Tricky not to break backward compatibility
    • Could disappoint some users
• Get rid of Sinatra in favor of a simple Rack-based app.
• Let it go, since we offer Docker installation

Sidekiq does a good job of this, including allowing to be wrapped with different access controls. I think it's just using rack, but can be mounted like a rails engine. https://github.com/sidekiq/sidekiq/tree/main/lib/sidekiq/web

Yes, they did an amazing job!

I'm wording it would be enough for us to have something as simple as https://github.com/rack/rack-contrib/blob/main/lib/rack/contrib/simple_endpoint.rb
