Sometimes it is not possible to reproduce failure in integration test locally. Adding html source code of page where failure happened should increase our ability to debug properly errors on the gates. For this purpose the addDetail method from testtools package is used. Following changes were done: * TestCase and AdminTestCase classes were modified in order to share common functionality and remove code repetition. * Testcases have been modified in order to use newly introduce class variables(TEST_USER_NAME, TEST_PASSWORD, CONFIG). * Methods _get_page_html_source and _dump_page_html_source have been created in the BaseTestCase class. _get_page_html_source uses javascript innerHTML attribute in order to make javascript modification to the page visible in the output. (javascript modificaton would not have been visible if webdriver's property page_source was used) Partially implements blueprint: selenium-integration-testing Change-Id: I064405337fb68c966da007f2a5bf91d5c0ec2b3d
