Add a new param 'vcpu_time' to virDomainGetCPUStats

Browse Source 
Currently virDomainGetCPUStats gets total cpu usage, which consists
of:

  1. vcpu usage: the physical cpu time consumed by virtual cpu(s) of
     domain
  2. hypervisor: `total cpu usage' - `vcpu usage'

The param 'vcpu_time' is for getting vcpu usages.
