numa_consistency: Update the threshold on ppc

qmp_command: add qmp 'node-name' expect value for blockdev

The disk device qemu command line has two configurations:
   1). blockdev config, eg:
       -blockdev node-name=file_image1,driver=file,filename=/var/**.qcow2
       -blockdev node-name=drive_image1,driver=qcow2,file=file_image1

   2). disk drive config, eg:
       -drive id=drive_image1,if=none,format=qcow2,file=/var/***.qcow2

If disk drive config, the expect value should be:
 {'device': 'drive_image1', 'qdev': 'image1', 'format': 'qcow2'}

If blockdev config, the expect value should be:
 {'node-name': 'drive_image1', 'qdev': 'image1', 'format': 'qcow2'}

Change image_chain to image_backup_chain for backup use

cache_sizes_test: set parameter cache-size for system image

memhp_threads: Add case to test prealloc_threads

Since winutils iso will be added directly when testing it
with windows guest. And cache-size is a qcow2 option,
it cannot be given to any imgfmt but qcow2.
To avoid it, just set this parameter to system image.
