teuthology-suite: add default machine type(smithi)

right now the default_machine_type fallback is set to None via some internal
mangaling, this makes users always have to pass --machine_type which mostly we
prefer to smithi's . Hence, making it a default unless otherwise, should be
helpful for users.
