Adding support of IMGOPTS (like in bash tests) allows user to pass a
lot of different options. Still, some may require additional logic.
Now we want compression_type option, so add some smart logic around it:
ignore compression_type=zstd in IMGOPTS, if test want qcow2 in
compatibility mode. As well, ignore compression_type for non-qcow2
formats.
Note that we may instead add support only to qemu_img_create(), but
that works bad:
1. We'll have to update a lot of tests to use qemu_img_create instead
of qemu_img('create'). (still, we may want do it anyway, but no
reason to create a dependancy between task of supporting IMGOPTS and
updating a lot of tests)
2. Some tests use qemu_img_pipe('create', ..) - even more work on
updating
3. Even if we update all tests to go through qemu_img_create, we'll
need a way to avoid creating new tests using qemu_img*('create') -
add assertions.. That doesn't seem good.
So, let's add support of IMGOPTS to most generic
qemu_img_pipe_and_status().
