The project dependencies have been updated, including a change from
WildFly 8.2.1 to 10.1.0. This change affects the project configuration
in several ways, specially in tests configuration.

The README.md file has been updated to reflect the configuration
changes.

The project configuration has been simplified by unifying some part of
the mysql and h2 configurations.

In addition, the project has been configured to allow the execution of
the application with the Maven WildFly plugin.
