include support for TomEE Maven Plugin

[simonjenga]

Inspired by the Jetty Maven Plugin, the TomEE Maven Plugin is a feature-rich plugin that allows for:

• Easy provisioning of a TomEE server
• Server start and stop
• Application deployment and undeployment

This plugin should be included in this project's Build file. The following are it's configuration details from a sample working environment:

<plugin>
    <groupId>org.apache.tomee.maven</groupId>
    <artifactId>tomee-maven-plugin</artifactId>
    <version>7.1.1</version>
    <configuration>
        <!-- Which flavor of TomEE to use? webprofile, plus, plume e.t.c default = webprofile -->
        <tomeeClassifier>plume</tomeeClassifier>
        <args>-Xmx512m -XX:PermSize=256m</args>
    </configuration>
    <!-- https://mvnrepository.com/artifact/org.apache.tomee.maven/tomee-maven-plugin -->
</plugin>

The following maven command was used to execute the Build, Deploy and Run:
mvn clean package -DskipTests -Dinvoker.skip=true tomee:run
