Workaround for "Service or property not registered:" problem does not work for single jar packaging

[mdzz]

The following comments are in StorageAccountExample.java:

        // When using the Java command line, a run time error similar to the following
        // was occurring:
        //          Exception in thread "main" java.lang.RuntimeException: 
        //          Service or property not registered:  
        //          com.microsoft.azure.management.storage.StorageManagementClient 
        //          interface com.microsoft.azure.management.storage.StorageManagementClient
        // To get around this, explicitly setting the ContextClassLoader works.
        //
        // This "hack" is not needed in IntelliJ.

However the workaround doesn't seem to work when the test program includes all the Azure SDK pieces in a single jar (through shading or jar-with-depedencies plugin). Allowing shaded SDK code to function will be very useful.

Was able to resolve the problem by:

• Manually specifying a provider configuration file.
• Use a newer version of maven-shade-plugin.
