core: improve balance selection of vm for migration

Iterate over source hosts, to find vm that can be migrated,
without over utilize memory or CPU of destination host.

Before was selected some random source host, and from this host
was selected single vm with minimum cpu usage,
but maybe with big amount of memory usage and
so over utilizied destination host memory.

In result we had that balancing not migrate any of vms.
