LXC driver doesn't support vcpu affinity yet, so just need
to modify it to support cpu shares.

Didn't test it, and not sure if it's the correct way to add cputune
xml for xend driver, and besides, seems "xm driver" and "xen hypervisor"
also support vcpu affinity, do we need to add support for them too?
Any suggestion on supporting cputune for xen is appreciated. :-)

When domain startup, setting cpu affinity and cpu shares according
to the cputune xml specified in domain xml.
Modify "qemudDomainPinVcpu" to update domain config for vcpupin,
and modify "qemuSetSchedulerParameters" to update domain config
for cpu shares.

These are pretty rough patches, something like a draft, I beleive
there must be many problems, please review it heavily, :-)

"shares" is to define the the proportional weighted cpu share
for the domain.
"vcpupin" is to define the cpu affinities of vcpus, it
