51% unit test of the deployment-handler

* only unit testing the /policy/components at the moment
* use -f Dockerfile_UT when building the image
* unit test runs inside docker container
* after docker run finishes copy the logs and coverage folder
  from docker container.  Sample commands:
  docker cp test_deployment_handler:/opt/app/dh test_logs/
  docker logs test_deployment_handler > \
   test_logs/$(date +%Y_%m%d-%H%M%S)_test_deployment_handler.log 2>&1
