Extend User Data Functions to Be More Like Azure Functions

I am a big fan of User Data Functions and their writeback capabilities.

However, as Fabric increasingly becomes the backend platform for storing, processing, and orchestrating data for front-end applications, something Fabric Apps is making increasingly apparent, we need more of the capabilities offered by Azure Functions.

I would love to see support for additional runtimes such as Node.js, TypeScript, and PowerShell, along with features like deployment slots.

Azure Functions are incredibly powerful, but many organizations struggle with the overhead of provisioning Azure resources. Bringing more of those capabilities directly into Fabric would lower barriers to adoption and accelerate innovation.
