Add support for az ad sp create-for-rbac equivalent in az-sdk-for-go

Feature Request

The az ad sp create-for-rbac subcommand is implemented in Python a non-trivial way.

It would be helpful if azure-sdk-for-go could provide equivalent functionality so that users don't need to translate the existing Python implementation into Go.
