Add coverage reports

[mauricioaniche]

We never calculated coverage because it was always tricky to configure Jacoco on a project that uses Jacoco as a dependency. But maybe we can make it work! We're all curious about what code coverage we have in Andy!

I can try this one!

Great!

I'd suggest to just try the basic jacoco configuration and see if a report comes out! If not, post the problem here and we will try to figure it out together!
