Container Registry: Allow specifying multiple scopes for a token in the AuthenticationClient

[vlieven]

Feature Request

The azcontainerregistry.AuthenticationClient provides two methods for token exchange: ExchangeAADAccessTokenForACRRefreshToken and ExchangeACRRefreshTokenForACRAccessToken. The documentation for both these functions defines the scope parameter as follows:

scope - Which is expected to be a valid scope, and can be specified more than once for multiple scope requests.

The API indeed seems to support passing multiple values to represent multiple scope requests, but the SDK only allows passing a single string value, making it impossible to actually pass multiple scopes. Would it be possible to change the interface to allow multiple scopes to be provided? Or add new function calls that allows specifying multiple values?

Thanks for the feedback! We are routing this to the appropriate team for follow-up. cc @northtyphoon @toddysm.
