> Currently in *getTokenSingleCall()*: if it get a HTTP failure response, it tries to consume
inputStream in httpUrlConnection, which will *always* lead to an *IOException* and this exception
never get checked in *AzureADAuthenticator*. 
>  As a result the httpStatus code is never checked in the retry policy of AzureADAuthenticator.
Tthat IOException will be caught by AbfsRestOperation, which will keep on retrying.
