ISSUE:       4267
TITLE:       Value of log_sweep parameter in trace configuration is ignored by trace plugin (assumed always true)
DESCRIPTION:
  Test check TWO cases:
  1) whether log_sweep = true actually lead to logging of sweep events
  2) whether log_sweep = fales actually prevents from logging of any sweep events (which is ticket issue).
