[os-win][requirements] FFE requested for os-win

Hi, I’d like to request a FFE for os-win. One important bug fix has missed the train (4.3.1) release, for which reason we’d need to have a subsequent one. The bug in question prevents Nova from starting after host reboots when using the Hyper-V driver on recent Windows Server 2019 builds. Thanks, Lucian Petrut
