The JaCoCo plugin has been added to perform the coverage test, while the
Wildfly plugins allows the automatic deployment of the project on a
Wildfly server using the 10990 port as the administration port.

The addition of the jboss-ejb3.xml file with the security domain
configuration allows the deployment of the "services" project as an
independent project in a Wildfly/JBoss container.

Some test classes have been refactorized for a more consistent use of
the OwnersDataset class and for a simpler test implementation.

The REST layer has been added but with incomplete tests. Students will
have to complete the tests.

This commit includes an important refactorization regarding tests. Test
classes and datasets have been moved from the "service" project to a new
"tests" project. This way, any project can include this "tests" project
as a dependency in order to have access to these common testing
resources.

This commit adds the OwnerService and PetService EJBs to the
implementation. This commit also includes the tests for this EJBs with
two different Wildfly profiles: a H2 profile and a MySQL profile.

The "administrator" entity has been added to represent the
administrators of the application.
