This commit fixes to show help messages of Tempest cli subcommands with '-h/--help' option such as 'tempest complete -h'. NOTE: 'deferred_help' param is for allowing deferring help print after initialize_app originally. But we can see the subcommand help messages with setting True to deferred_help now[1].
