[dts] [PATCH V1] framework qemu_kvm.py: Add "server" and "multi_queue" parameter for more qemu launch option and adjust some timeout setting to improve the test stability

[Yao, Lei A]

Hi, Yong

Only part test cases will use this parameter, so I don't want add it to the .cfg file but keep them in the tests file. Then I can use common .cfg file to different vhost/virtio test cases. 
For the comment, I can add most info in the commit log in the V2 patch. Thanks
