Please review code for supporting change test execution status in JIRA
Maybe I am overlooking something, but it actually seems to me that it's pointless to set `--jira_username` & `--jira_password` in three different places = since we always set those arguments to pytest.

Therefore I'd advise it to simply set them once at the beginning right after beginnign of `trigger_pytest`, where `pytest_arguments` variable is declared for the first time
