This is the v1 of guestperf multifd migration support

It is merely the same as the original patch, just change the maintainer,
since the ./scripts/get_maintainer.pl do not get the maintainer of 
tests/migration before this patch:
https://lore.kernel.org/qemu-devel/842e7cbd-a444-04ac-35d5-168c6415441e@redhat.com/

Guestperf tool does not cover the multifd-enabled migration currently, it
is worth supporting so that developers can analysis the migration performance
with all kinds of migration. 

Please review, thanks.

Guestperf tool does not cover the multifd-enabled migration
currently, it is worth supporting so that developers can
analysis the migration performance with all kinds of
migration.

To request that multifd is enabled, with 4 channels:
$ ./tests/migration/guestperf.py \
    --multifd --multifd-channels 4 --output output.json

To run the entire standardized set of multifd-enabled
comparisons, with unix migration:
$ ./tests/migration/guestperf-batch.py \
    --dst-host localhost --transport unix \
    --filter compr-multifd* --output outputdir
