Roman Bogorodskiy 387543c57f bhyve: support vcpu pinning 
Bhyve supports vcpu pinning using the `-p vcpu:hostcpu`
argument. This argument can be specified multiple times for the same
vcpu to pin it to multiple hostcpu's.

Bhyve currently does not allow to change vcpu pinning configuration for
the VM that is already running.

Use this to support domain's vcpupin configuration such as:

  <cputune>
    <vcpupin vcpu="0" cpuset="1,2,3"/>
  </cputune>
