The new quarantine feature for chrome cleanup tool needs a finch switch to control it.
It adds "--quarantine" into the command line when launching the cleaner if the switch is enabled.
It will be only enabled on the cleaner. So only adds switch to the cleaner, but not to the reporter.
Default is disabled.
