unable to specify PlanStagingMode when deploying an app online

[httpants]

The ApplicationsDeployer.__deploy_app_online method currently does not have a plan_stage_mode parameter, so all applications are deployed with the default PlanStagingMode of nostage, even if you specify staged in the model.

For example this model will result in the DbAdapter application being deployed with a PlanStagingMode value of nostage...

appDeployments:
    Application:
        DbAdapter:
            SourcePath: '@@ORACLE_HOME@@/soa/soa/connectors/DbAdapter.rar'
            PlanStagingMode: stage
            ModuleType: rar
            PlanPath: '@@DOMAIN_HOME@@/DBAdapterPlan.xml'
            Target: DefaultServer
