Fix to show cli subcommand help message

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].
