In some enterprises, the default bootindex is -1 for system disk,
which means cancel the boot index.
If hotplug a data disk then reboot guest, qemu may set the data
disk with higher bootindex, which depends on different enterprises'
policies.
As above, need set bootindex=0 for system disk.

1. case logic is wrong, there are 2 types in the configuration, 1 is balloon_check, the other is kernel_install, actually kernel_install is the case which will be executed.
2. no need to match qmp output pattern now.
3. balloon_check_qmp steps can be covered in balloon_check with qmp, and no scenario about kernel_install and balloon_check.
