Add test that egitutils/openshift does not include untracked files in dirty check nor will commit these untracked files

usecase:

EXECUTE: Create openshift project
EXECUTE: Make sure all is committed and Pushed.
EXECUTE: Edit an existing committed file - commit it.
EXECUTE: Add a "xyz.log" file that is not to be committed.
EXECUTE: Publish to server.
ASSERT: no message about dirty changes, everything should be committed. Only message about push is missing.
EXECUTE: Wait for publish to finish.
ASSERT: "xyz.log" should not be pushed nor committed.
