Print collected variables and artifacts at the end of Workflow

- add "logGlobalVariables" boolean parameter for function runScenario()
  which enables printing the collected during scenarion execution
  global_variables *before* the "finally" section execution
  (to not wrap the finally section in another try/catch in case
  of failures)
