Cloud platform integration

Start by reviewing the proposed GitHub Actions workflow inputs and the ASGI application deployment flow described in the issue. Clarify the cloud service, usage-based billing, deployment behavior, and admin portal requirements before implementation; done would include publishing an application and exposing its app name, resources, and cost.

Current Situation

We have no convenient way of integrating with cloud platforms.

Proposed Actions

We should consider providing auto-configuring ReactPy as a paid cloud service. To oversimplify the design:

1. The user will pay a usage based hosting fee
2. We will develop GitHub actions workflow that publish a ReactPy application to the cloud
3. The GitHub actions workflow will need the following info
   • cwd_dir : The cwd directory for us to cd into before executing commands.
   • application_path: The dotted path to my.asgi:application, which is directly provided to an ASGI webserver we auto-configure.
   • site_api_key: Unique key that tells us what user account (and site tied to the user) is being published
   • app_name: Name of the app. The user will be able to view their published apps within an admin portal, and see resources/cost for each app. If a user attempts to deploy an app with the same name as an existing one, we will overwrite the existing app.
