Enable Maven use for builds and more

[poikilotherm]

Inspired by https://github.com/payara/Payara/tree/master/appserver/extras, it would be nice to look into using Maven for images and maybe more.

We could try to compile Dataverse as a submodule. When that submodule would allow for packaging an installation bundle (instead of using automake), it would greatly ease image building and reduce complexity.

It might also be used to replace Skaffold with the right plugins to deploy images to a cluster. (Or integrated with a custom skaffold build call to Maven). IIRC there are Maven plugins for docker-compose, too.

Using JIB is so easy...

        <profile>
            <id>jib</id>
            <properties>
                <skipUnitTests>true</skipUnitTests>
            </properties>
            <build>
                <plugins>
                    <plugin>

                        <configuration>
                            <from>
                                <image>docker.io/payara/server-full:${payara.version}</image>

                            <to>
                                <image>docker.io/gdcc/dataverse-k8s</image>

See https://github.com/poikilotherm/dataverse/tree/5292-mvn-container and IQSS/dataverse#7245 for progress on this, not using JIB but still having exploded WAR.
