Example: Grpc 🚀

[josephaw1022]

Simple grpc example to show display how service discovery works in aspire.

Also might want to show how to integrate with the new yarp extension packages from aspire.

Is it even doable? Could not find any docs about it

The 'AspireShop' example has a gRpc service (BasketService') and extension functions that explain how to resolve the service reference. It also has examples on health checks of the service.
