[libvirt] [PATCH 4/6] cputune: support cputune xml for LXC driver
LXC driver doesn't support vcpu affinity yet, so just need
to modify it to support cpu shares.
* src/lxc/lxc_controller.c (Setup cpu shares for domain)
* src/lxc/lxc_driver.c (Update domain config when "lxcSetSchedulerParameters"
is invoked)
