The IsEqualToEntity matcher (previously, IsEqualsToEntity) has been
improved to allow property comparison by functional reference to the
getter methods of the properties to compare. Specifically, the
"checkAttribute" methods added allow providing a Function<T, R> as a
getter, where T is the type of the entity to compare and R is the type
returned by the getter method.

Some test of the service and rest projects have been updated for better
coverage, achieving a 100% coverage in most of them.

The README.md has been update to reference the new course and the new
Eclipse version. In addition, the general pom.xml file has been updated
to include the newer versions of the dependencies, and the ear/pom.xml
has been modified to include more project information in the generated
EAR.

On the other hand, the testing mysql-ds.xml have been removed and the
standalone.xml testing files have been updated to include the datasource
data.

Missing version for compiler, javadoc, source and deploy plugin in POM was
causing some warning messages during the compilation with Maven.

In addition, the Javadoc was fixed in the OwnerService and PetService
classes.

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.
