Many thanks for this PR.

I have allowed the CI, as it's your first PR on QuickPerf.

The builds have failed:

/home/runner/work/quickperf/quickperf/testng/testng-sql-listener/src/test/java/org/quickperf/testng/sql/QuickPerfSqlTestNGListenerTest.java:[3,28] cannot find symbol
  symbol:   class TestNGTests

Adding this dependency to the new Maven module should fix the issue:

        <dependency>
            <groupId>org.quickperf</groupId>
            <artifactId>quick-perf-testng-test-util</artifactId>
            <version>1.1.1-SNAPSHOT</version>
            <classifier>tests</classifier>
            <type>test-jar</type>
            <scope>test</scope>
        </dependency>

Could you also please add a license header to each new file?

Thank you.
