check: add CLI option to repeat and stop tests in case of failure

Currently with -i <n> option the test can run for many iterations,
but in case if we want to stop the iteration in case of a failure,
it is much easier to have such an option which could check the
failed status and stop the test from further proceeding.

This patch adds such an option (-I <n>) thereby extending the -i <n>
option functionality.
