Pull Request for Work Unit 1 -

FS2 source removed from Service Nucleus. 
Fixed test case failures in karyon-admin.

FS2 Source Resolution:
--------------------------------

The FS2 source and its related tests are removed from the service nucleus and added as a local jar file dependency since the builds cannot pull it from nexus.

In order to allow addition of .jar files, the jar entry in .gitignore is commented out.

the library is pushed to /service-implementation/lib

Test case failure resolution:
---------------------------------------
The root cause of the failures were identified to be the configurations required for the successful execution of the tests were reset when the tests are executed in the random order. The issue was resolved by re configuring the properties before the run.
