OSTF tests are failed when execute them by suite

[Oleksandr Kyrylchuk]

Cloudv OSTF adapter fails to execute more than one test for each suite.

Steps to reproduce bug:
1. Enter into ostf container
2. Run ostf test suite, which contains more than one test:
{code}cloudvalidation-cli --show-full-report --config-file=~/test.conf cloud-health-check run_suite --validation-plugin-name fuel_health --suite fuel_health.tests.sanity.test_sanity_identity.SanityIdentityTest{code}

Expected result:
Two tests passed successfully
Actual Result:
First test pass, second test is failed with error:
{code} File "/usr/local/lib/python2.7/dist-packages/fuel_health/test.py", line 88, in setUpClass
assert not hasattr(cls, attr_name)
AssertionError: {code}

This bug is not going to be fixed in Fuel OSTF.
For now we should just comment this assertion after installation of fuel-ostf.
