These series makes tests pass with
IMGOPTS='compression_type=zstd'
Also, python iotests start to support IMGOPTS (they didn't before).
v2:
01: add Max's r-b
02: simplify a lot: just add separate -o for IMGOPTS.
also, don't bother with catching compat=0.10
03,04: new
05: add Max's r-b
06: one more explict compression_type=zlib
07: new
08: reduced to only update filter_img_info
09: adjust commit message, add comment, add Max's r-b
10: s/ = 0/ &= ~QCOW2_INCOMPAT_COMPRESSION/
add Max's r-b
11-13: add Max's r-b
14: one more regex for "2, 3, 4" case
15-16: add Max's r-b
17: new
