[qa] 'run_single_ostf_test' method checks results of all OSTF tests which were performed

[Artem Panchenko]

In system tests we use 'run_single_ostf_test' method to run some exact OSTF test and check its results. But after OSTF test is finished that method checks results of all OSTF tests performed for cluster earlier and returns exception in case of failures, for example:

http://jenkins:8080/view/5.0_swarm/job/5.0_fuelmain.system_test.centos.thread_5/60/testReport/%28root%29/ceph_ha_restart/ceph_ha_restart/
https://github.com/stackforge/fuel-main/blob/master/fuelweb_test/tests/tests_strength/test_restart.py#L150

I think we should modify 'assert_ostf_run' method to have ability to checks results of some particular OSTF tests.

    Check results of one test in run_single_ostf_test

    In 'run_single_ostf_test' method we run only one health
    check for environment and expect that it will pass. So
    we should verify only its results, because some other OSTF
    tests сould fail earlier.

We appear to have a clean fix to the tests, upping to high so that we can attempt to back port this.
