TestNG optional reporting for @After @Before failures #356

I'm submitting a ...

• feature request

What is the current behavior?

On Before/After(Class/Test) failures allure create reports as it was 'Test' and we have some inconvenience to displaying TeamCity allure reports. For example, next test class will report about two tests(one failed and one skipped)
public class Mytest { @BeforeMethod public void before() { Assert.fail(); } @Test public void test() { } }
This behavior was implemented with #135

What is the expected behavior?

Reporting of After/Before method to be optional. For example, using configuration flags.

What is the motivation / use case for changing the behavior?

Disabling the After/Before reporting was requested a sew times ago and those requests was rejected because of #135. My call is to make it optional to satisfy both behaviors with actual by default.

Please tell us about your environment:

| Test framework | testng@6.14.3 |
| Allure integration | allure-testng@2.9.0 |
| Generate report using | teamcity allure plugin |
