[functional][y] Check if wicked is running for yast command line tests
|Category:||Enhancement to existing tests|
|Target version:||QA - future|
As per comment in https://bugzilla.novell.com/show_bug.cgi?id=1148679 Josef has stated that tests require wicked to be running, as yast2 lan in general is useful in case of wicked only.
So, executing this test with NM doesn't make sense in general.
Therefore, test should be executed with wicked setup only. Additionally, we can add such check to simplify investigation, as in case wicked is down, tests will fail.
