Allow starting of multiple containers

[rhuss]

This should be possible with multiple execution configurations for the plugin. The stop goal already takes care for shutting down multiple containers.

There should be at least a good example in the documentation how using multiple containers should be possible.

Maybe using a dedicated <containers> configuration element is less verbose is easier to understand. Also, one would have more control over the startup order (which is important when it comes to linking containers).

Am I misunderstanding something, or isn't this possible already?

Currently I'm doing something like

<configuration>
    <images>
        <image>
            <name>tpires/neo4j</name>
            <run>
                <ports><port>17474:7474</port></ports>
                <wait…/>
            </run>
        </image>
        <image>
            <name>${docker.org}/${docker.image.prefix}candidate:${project.version}</name>
            <run>
                <ports><port>candidate.port:8080</port></ports>
                <env>
                    <NEO4J>http://${docker.ip}:17474</NEO4J>
                </env>
                <wait…/>
            </run>
        </image>
    </images>
</configuration>

in a start execution. That indeed spins up two containers.

Ah, sorry, forgot to clean up this issue. In fact the main reason for changing the the configuration format in 0.10.1 was to introduce the possibility to start multiple containers.

Thanks for pointing this out ;-)
