tests: provide an option to mark tests as 'flaky'

* also add some time gap in other tests to see if we get things properly
* create a directory 'tests/000/', which can host any tests, which are flaky.
* move all the tests mentioned in the issue to above directory.
* as the above dir gets tested first, all flaky tests would be reported quickly.
* change `run-tests.sh` to continue tests even if flaky tests fail.
