CPU and rate pollsters in the compute agent

In this CR rate and cpu pollsters for the libvirt hypervisor
is implemented.

This stuff is required for the support cpu_util, disk.*.rate
and network.*.rate pollsters storing without any trasnfomers
work. We need this supporting because coordination of
a notification agent (which makes trasnformations) doesn't
work good and enough for the performant and consistent
sample transformations.
