Adding tests for kompose-specific labels and buildconfig dockerfile construct

* Two new scripts testing kompose-specific labels have been added:
	script/test_in_openshift/tests/routes-service-expose-hostname.sh
	script/test_in_openshift/tests/routes-service-expose-true.sh

* Tests for buildconfig dockerfile construct has been added:
	script/test_in_openshift/tests/buildconfig_dockerfile.sh

* Tests for restart option:
	script/test_in_openshift/tests/restart-options.sh

* Ability to run individual scripts: Changes have been made to script/test_in_openshift/run.sh
  for running individual scripts:

	Eg. ./script/test_in_openshift/run.sh script/test_in_openshift/tests/routes-service-expose-true.sh

script/test_in_openshift/run.sh
