Allows alternative way of setting default container configuration in arquillian.xml:
<container qualifier="openshift">
<configuration>
</configuration>
</container>
<container qualifier="openshift2">
<configuration>
</configuration>
</container>
<extension qualifier="container-selector">
<property name="default">openshift1</property>
</extension>
This allows you to set active container via Maven property filtering, thus in a much more friendly way for an IDE. This extension disables default ContainerExtension.
