[PATCH v1] introduce multifd into guestperf

[huangy81]

From: Hyman Huang(黄勇) <huangy81@chinatelecom.cn>

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:
842e7cbd-a444-04ac-35d5-168c6415441e@redhat.com/">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.
