/**
* Notifies TestNG core skipping remaining tests after first failure has appeared.
*
* Enabled when -DtestFailFast=true
*
* This is a workaround for https://issues.apache.org/jira/browse/SUREFIRE-1762 since
* the bug makes the built-in fast-fast feature `-Dsurefire.skipAfterFailureCount=1` unusable.
* Maven Surefire version 3.0.0-M5 contains the fix, but that version is unusable because of problems
* with test output, https://issues.apache.org/jira/browse/SUREFIRE-1827.
* It makes the Pulsar integration tests slow and to fail.
*
* This implementation is based on org.apache.maven.surefire.testng.utils.FailFastNotifier
* implementation that is part of the Maven Surefire plugin.
