Separate job for testing live-migration with different storage
configurations(No shared storage/NFS/Ceph was implemented during Mitaka and
available to be executed using experimental pipeline.

The job is ready but shows same stability as
Bugs like [1] [2] affects its stability. So the main idea for now it to
make this job running against latest libvirt/qemu versions. Markus Zoeller
and Tony Breeds are working on implementation of devstack plugin for that
[3]. So once plugin ready it will be possible to check. Another option for
this is to use Xenial images in experimental job, which will contain newer
libvirt/qemu version. Infra team already add ability to use 16.04 for
experimental[4], so I'm going to try this approach.

Work items:
- Cover negative testcases for live-migration(to check that all rollback
logic works well) - in progress;
- Check state of VM after migration
- Live migration for instance under workload
