[00/14] iotests: support zstd

Hi all!

These series makes all test pass with

   IMGOPTS='compression_type=zstd'

Also, python iotests start to support IMGOPTS (they didn't before).

Also, tests works if enable compression type zstd by default. There is
no such config option currently, probably it will appear in future or
we'll go some another way (like external config file, like
/etc/qemu.conf). For now you may test with a simple patch like:

    --- a/block/qcow2.c
    +++ b/block/qcow2.c
    @@ -3539,6 +3539,11 @@ qcow2_co_create(BlockdevCreateOptions *create_options, Error **errp)
                 goto out;
             }
         }
    +
    +    if (!qcow2_opts->has_compression_type && version >= 3) {
    +        qcow2_opts->has_compression_type = true;
    +        qcow2_opts->compression_type = QCOW2_COMPRESSION_TYPE_ZSTD;
    +    }
     
         if (qcow2_opts->has_compression_type &&
             qcow2_opts->compression_type != QCOW2_COMPRESSION_TYPE_ZLIB) {

We want to use zstd compression type by default in Virtuozzo 8. This is
the first step, which is good anyway: improve iotests.
