[dts] [Feature request] Add vm vf mac, login password in the scenario test

[Xu, Qian Q]

Hi
I have tried the scenario test and found that login password is not supported, and the VF's MAC setting is also not supported. I requested the features as below:

1.       Add the config about VF MAC in the scenario config file.

2.       Add the config about VM login password in the scenario config file.

Many thx.

Thanks
Qian
