Add Artifact.SCOPE_PROVIDED artifacts to aggregate report

[chonton]

I have an aggregate maven project where one of the projects must be scoped as 'provided'. I would like it to be still considered for inclusion in the aggregate report.

@chonton Thanks for the contribution! May I ask you for your use case? Especially it looks like my current assumptions do not hold true:

1. A separate project only for the purpose of creating the coverage report is required. In your case it looks like you can rely on a existing project.
2. My understanding of usage of scope PROVIDED is a dependency on a common API (like Servlet) which is typically not part of the reactor itself. Our goal can only create reports for projects from the reactor.

[chonton]

My typical reactor project has three modules:

• api (interface jar)
• service (implementation delivered as a docker image)
• test (integration tests in a docker image)

Both service and test have a compile dependency on api. Additionally, test has a particular dependency on service; the service module must be built before test so that service docker image can be launched during pre-integration-test phase, and the classes from service should not be included in the compile or runtime classpath of test.

To prevent the service classes from being included in the test docker image, the dependency cannot be compile or runtime. The jacoco aggregate goal uses test to distinguish the projects that provide coverage without providing code.

This leaves provided, which seems correct, as the service is providing the implementation of api.

@chonton Indeed, this is nice use case where the aggregate-report works well. Thx!

@Godin Do you agree to merge this? If so I we need to add a change log.

@marchof and @Godin, anything else required to merge this PR?

[Godin]

I don't think that we need this update of Javadoc.

@chonton not so much - I just need to come from vacation back to work 😉
