Implement Azure Developer CLI template

[jjgriff93]

The solution should be easily deployable using the Azure Developer CLI (azd) and listed in the AI App Templates.

Getting started commands should be as simple as:

• azd auth login
• azd env new dev --location uksouth --subscription {guid}
• azd up

Encountered an issue with the service deployment through azd up due to copy ignoring symlinked common folder:

ERROR: error executing step command 'package --all': failed packaging service 'app': open /var/folders/kl/dwz9d6xx5jx9s3ygwtqc5q_c0000gn/T/azd2971955672/common: no such file or directory

Raised an issue on azd: Azure/azure-dev#4715

Potential workarounds to explore:

• Prepackage hook that copies api code and common folder contents into a dist that's referenced by azure.yaml
• Re-hosting as container apps
