Offer contextual guidance for lack of $select statement on GET requests #51
Description
When intercepting Graph GET requests that don't include the $select parameter, we should highlight it and instruct developers to optimize them by adding $select with the list of properties they'd like to retrieve. Request without $select are slower because they potentially retrieve more data than actually needed in the app. Specifying the set of properties to retrieve would not only lower the load on Graph but also speed up the app.
Consideration: since there might be cases where apps need the whole data set, we should either allow to suppress this suggestion on specific requests or disable it altogether to avoid returning messages that aren't relevant.
