Assume there's no way to pass the possible FUA flag through to oVirt here?
We have flush=true, which send nbd flush command after the write/zero.
Maybe we could handle flush=true as fua when using nbd backend, I'm not sure
how important is this.
I think we miss converting fua to flush=true to have full api 2 support.
Any copy program ought not to set this flag on general writes/zeroes,
so it's not really important for pwrite/zero, but a nice to have.
However nbdcopy has a --flush flag which sends a flush command to the
destination when the copy has finished. We ought to obey this one.
