Review comment:
No particular benefit. Because `LoadTest` is no longer a subclass of
`unittest.TestCase`, I had to move this code somewhere. And the reasons why I
stopped using `unittest.TestCase` are:
- We had to prevent load tests from being included in other test suites and
that's why `LOAD_TEST_ENABLED` guard was used. Now the guard is no longer
needed,
- `tearDown()` was actually used to run a pipeline, which was misleading, as
tearDown is supposed only to clean up resources after test execution,
- Without nose or pytest, it is difficult to pass extra command-line
arguments.
To sum up, I think `unittest` doesn't suit our needs here and can be easily
replaced with plain Python classes.

> The community is considering moving away from nose to pytest:
> https://issues.apache.org/jira/browse/BEAM-3713. We should change the way of
> running Python load tests: instead of being subclasses of
> `unittest.TestCase`, they could be plain Python scripts, just like wordcount
> examples. This will bring one additional benefit: _LOAD_TEST_ENABLED_ guard
> will be no longer needed and could be safely removed
