[ELY-2480] Add code coverage to the project

[Dkafetzis]

https://issues.redhat.com/browse/ELY-2480

Added a new profile in maven to run test coverage for the elytron project. The profile name is "test-coverage"
Running the following will run the test coverage
mvn clean install -Ptest-coverage

Hi @Dkafetzis , thanks a lot for the PR!
I have a question, I can see in the resulting file at path/to/wildfly-elytron/target/jacoco-ut/org.wildfly.security.http.basic/index.html that the coverage for BasicAuthenticationMechanism is 0% . We have tests for this mechanism in the module tests/base. Is that something that can be taken into account when generating the report?

[Dkafetzis]

Hello @Skyllarr, Yes i see now that some tests are not included in the coverage report. I'll look further into this, any suggestions on this are welcome.

@Dkafetzis I tested this change using the latest 2.x code and I'm getting the following exception:

As a suggestion, we can use the latest version of OpenClover - 4.5.2

[Dkafetzis]

I updated it to the latest version. It works now on my machine, but feel free to try it out. Also try running it with mvn clean install -Ptest-coverage org.openclover:clover-maven-plugin:aggregate org.openclover:clover-maven-plugin:clover

@Skyllarr Can you also test this change? I'm still getting the below exception in my environment. Thanks!
