/**<pre>
 * GWT usage note:
 * The hosted engine tab model implementation. To keep it DRY this model is used in Host install and new host views by
 * connecting it to a tab using the xml.
 * This model has currenly a list of {@linkplain org.ovirt.engine.core.common.businessentities.HostedEngineDeployConfiguration.Action}
 * which is translated into radio buttons by each of the view classes, by using a ListModelRadioGroupEditor
 *
 * The {@linkplain #actions} are the set of deploy operations options presented by the radio button, essentially its meant
 * to DEPLOY the hosted engine agent, or UNDEPLOY it. NONE means the host installation will not touch hosted engine components.
 * See {@link org.ovirt.engine.core.common.businessentities.HostedEngineDeployConfiguration.Action}
 *
 * Future additions to this model may include more customizations to pass to the installation.
 * </pre>
