Add /status page

[florian-vuillemot]

What would that feature address Add monitoring facility for external tools as sonde. Calling "/" of an application can have side effects (computation, db connection, etc.).

Description of the ideal solution Application monitoring uses to call a "/static" page on an application to know if the application is still running. Information like "websocket are up" is a plus.

Caveats Users can want to provide other information on this page for internal needs. Taipy can not handle this custom behaviour but should allow users to do it. Ex: Ensure that my application can still communicate with an external tool.

Acceptance Criteria

• [ ] This page should be resource-efficient.
• [ ] Doc on the page for dev and operator.
• [ ] Doc for customization of this page.

After a enlightened comment from @FabienLelaquais the status.html page is now a status.json

{
  "backend_version": "1.2.0", 
  "flask_version": "2.1.0", 
  "frontend_version": "1.2.0", 
  "host": "127.0.0.1:5000", 
  "python_version": "3.10.1 (tags/v3.10.1:2cd268a, Dec  6 2021, 19:10:37) [MSC v.1929 64 bit (AMD64)]", 
  "user_status": "on_status(state: State)"
}

Which is way better !
