Aleksei Zakharov 4719ec15e9 qemu: add per-vcpu delay stats
This patch adds delay time (steal time inside guest) to libvirt
domain per-vcpu stats. Delay time is an important performance metric.
It is a consequence of the overloaded CPU. Knowledge of the delay
time of a virtual machine helps to understand if it is affected and
estimate the impact.

As a result, it is possible to react exactly when needed and
rebalance the load between hosts. This is used by cloud providers
to provide quality of service, especially when the CPU is
oversubscribed.

It's more convenient to work with this metric in a context of a
libvirt domain. Any monitoring software may use this information.
