This patch adds "info disk-deadlines" qemu-monitor option that prints
dump of all disk requests which caused a disk deadline in Guest OS
from the very start of Virtual Machine:

qapi interface review only:

Should it be possible to filter to deadlines missed for a specific node,
by having an arguments with an optional node name?

Should any of the existing query-block or similar commands be modified
to make it obvious that there are missed deadline stats, and that it
would be useful to call query-disk-deadlines to learn more about them?
Also, should there be an event raised when a timeout occurs, so that
management doesn't have to poll this API?

ok, this seems a nice addition
