nova-live-migration: Ensure subnode is fenced during evacuation testing
As stated in the forced-down API [1]:
> Setting a service forced down without completely fencing it will
> likely result in the corruption of VMs on that host.
Previously only the libvirtd service was stopped on the subnode prior to
calling this API, allowing n-cpu, q-agt and the underlying guest domains
to continue running on the host.
This change now ensures all devstack services are stopped on the subnode
and all active domains destroyed.
It is hoped that this will resolve bug #1813789 where evacuations have
timed out due to VIF plugging issues on the new destination host.
