New feature to include method reference in RFC metric

[maykon-oliveira]

• Now the method reference calls are counted in the RFC metrics

• I updated the pom to use Junit 5

This new version has a readable api and some useful things, such as @DisplayName, to declare more friendly names for test cases.

All old tests are ok with the new version of Junit, I had to change the package of some annotations, but everything works.

Hi, @maykon-oliveira! Thanks for the PR! The way it is now, it's just very hard to review, though :/

I would need you to:

1. Your IDE replaced tabs to spaces. This means you basically changed all files in the project.
2. Split the PRs in two. One that moves things to JUnit 5 (thanks for that), and another one that adds the new functionality to RFC. (Note that codecov says that coverage went down significantly, so I imagine some tests are not being run by the coverage tool anymore?)

Cheers!

[maykon-oliveira]

Sure, it's better. I will create two pull requests, one with Junit update, and other that adds the new functionality to RFC.

@maykon-oliveira Now, we are ready for this PR, right?
