AAD integration auth using DLL and ADAL4J

[AfsanehR-zz]

If operating system is Windows, use DLL to authenticate with integrated authentication mode, otherwise use ADAL4j dependency.

If DLL is not loaded or operating system is not windows use ADAL4J.

Note: This PR fails for now because it requires ADAL4J 1.4.0 release
