      1. Add custom load metric module as a resource to org.wildfly.extension.mod_cluster module: 
        <resources>
    <resource-root path="mod_cluster-custom-metric.jar"/>
    <resource-root path="wildfly-mod_cluster-extension-[version].jar"/>
</resources>
      2. Add <module name="org.jboss.as.server"/> as a dependency to org.wildfly.extension.mod_cluster module
      3. Restart server

      1. Start Wildfly
      2. Add custom load metrics with 'module' defined
      3. Reload

      This message shows up if I try to define module attribute for 'custom-load-metric'. It doesn't make sense, since it says both, that 'module' attribute is and isn't allowed. This also means, that the module attribute is not usable.
