new feature: Support for client secret auth against azdls

[twuebi]

Feature Description

It seems that azdls-service currently only supports sas / sharedkey / imds auth but it doesn't support the client_secret auth method which would work with app registration / entra id.

Problem and Solution

This feature enables using azdls with microsoft app registration. It should either take care of refreshing / logging in again, e.g. via some background task / checking expiry before issuing a request or expose the means to refresh tokens to the user, e.g. via some Arc<RwLock<Token>> which is exposed on the api.
