Create an Exercised Plugins Report

This feature permits the creation of a report that describes
which plugins were exercised and what versions were used.

Two reporter types are available. The default "Console" reporter and
the "Text File" reporter.

The Text File reporter creates a java properties file and is useful
when wanting to be able to see which plugins and their versions were
tested with a particular version of Jenkins Core.

> Or do you mean in the InstalledPluginReporter interface?

Especially in the interface so implementations can decide what to do (including ignoring it).

> Do you mean that include the test name in the properties file?

It depends on your use case. Here is what I prefer:

- purge file between test suite runs to avoid junk accumulation (putting the file to target/ would help)
- track plugin usage for particular test (current implementation lists all plugins that was installed for at least one test)

Yes `plugins.GerritTriggerTest::gerrit-trigger = 2.11.1` would work for me
