[feature] hyper live migration based on qemu and kvm

[resouer]

We ( @xlgao-zju @Crazykev ) are implementing hyper vm live migration based on existing kvm hypervisor and qemu. Just fire up this issue to let anyone interested know and close the old one: #35 .

For now, we have tested qemu savevm/loadvm on the same node, it works. And we also figured out virtfs is not available to support live migration. We now use devicemapper backend to hold docker image.

Here's our work to track:

• test qemu live migration with hyper & kvm & devicemapper
• test cross host live migration with qemu & hyper, need share storage of the two nodes (use NFS for now)
• refactor hyper side to load a freshly migrated vm
• add commands to start qemu and migrate vm in hyper

Will update this list whenever we have new progress.

This is very interesting, and we'd love to see the PR. If there is a working beta in the next two weeks, we could throw a demo at the coming DockerCon at Barcelona!
