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.

During the review of the repository split, it was pointed
out that 'agnostic' was a rather strange word, so we'll go
with 'generic'. I opted for not rebasing the PR, since I
had many problems when trying to do so.

This will make it easier when we're splitting these
tests into their own repositories.

Some case will try to create images in shared/data/,
but it should be in shared/data/images/, update the
cfg file of these cases, so that it can create the
images in correct directory.

These tests will create some other format of image, so the
options for qcow3 would affect them.
To make these cases still work with qcow3 format, reset the
'image_extra_params' parameter in them.

We've only spot this mistake now :(

In order to have self describing tests, split the original
subtests.cfg in several per test files, and create subtests.cfg
out from this information.
