hs-test: add test suite features
Test suite now supports assertions which on fail stop test case run, also it allows to create docker containers which are going to be stopped automatically after the test run is finished. Type: improvement Signed-off-by: Maros Ondrejicka <maros.ondrejicka@pantheon.tech> Change-Id: I2834709b1efd17b8182d36cc0404b986b4ed595d Signed-off-by: Filip Tehlar <ftehlar@cisco.com>
