ktest: Added force stop after success and failure
Added the options STOP_AFTER_SUCCESS and STOP_AFTER_FAILURE to allow the user to give a time (in seconds) to stop the monitor after a stack trace or login has been detected. Sometimes the kernel constantly prints out to the console and this may cause the test to run indefinitely. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
