> Currently WASB throws a IOException in read and seek API for both Block and Page blobs
for scenarios where the backing blobs do not exists. This creates problems for applications
like HBase which expect a FileNotFoundException in these scenarios. 
> The fix for the problem is to check if the exceptions from Azure storage is because for
Blob not found and throw FileNotFound exception if that is the case.
