[Feature request] Auto generated (zero-code) backend service

**Is your feature request related to a problem? Please describe.**
Azure Static Web Apps is an awesome service. The deployment process and the Azure Functions backend are super cool and super easy to use.

But one thing is frustrating - the backend side. Adding a basic functionality that evolves DB (super common), makes things a little bit complex: Adding separate Azure Resource of CosmosDB or SQL Database, creating functions for access that DB, implementing security rules manually in the functions, etc.

I love the Azure Static Web Apps, and I use it for several projects. But most of the time, I'm finding myself wasting a lot of time by implementing simple backend services for basic resources CRUD operations.

**Describe the solution you'd like**
There are competitor services that took the backend one step further by configuring DB and security rules in some UI interface (zero-code) and auto-generates a simple backend service that allows you to access the data easily and keep your focus on your app business logic.

I would like to see such a thing here as a Microsoft solution.

**Describe alternatives you've considered**
An example of such a thing in Azure Static Web Apps can be done by auto-generate Azure database resource internally in the Azure Static Web Apps resource (like you do for the CDN and Azure Functions) and auto-generate API/Azure Functions from JSON/JS config (no UI is needed).

The JSON/JS config can define the resources' structure, the collections, security rules, allowed CRUD operations, etc. And on the deployment, Azure Static Web Apps will auto-generate API/functions to access those resources (like you generate `/.auth/...` you can generate `/backend/...` from that JSON/JS config.

Simple as that, no UI and no new SDKs are needed, just configure the commonly used backend with simple JSON/JS, and auto-generate the backend for the developer.

**Additional context**
This suggestion is an additional feature, not a replacement for the existing Azure Functions support. So, the developer will be able to use auto-generated backend, and custom complex additional functions.

I think this feature will take Azure Static Web Apps one step further.
