[2136] added some misc changes

Changes in b10-stats_test.py:
 - added deeply checking statistics values of each of module and
   instance

 - added stats_server.shutdown() at the end of the test_config method.
   Because the running stats_server was never shut down even after
   stats_server.run() was invoked.

Changes in test_utils.py:
 - Changed the way of invoking multiple auth instances just for efficiency
