Unhardcode live_migration_tunnelled

As we do not have shared instance storage configurable for computes,
live migration with block migration is the only live migration
type choice for VMs not booted from cinder volumes.

At the same time we have uncoditionally enabled
"live_migration_tunnelled" option in nova.conf that is NOT
compatible with block migration (see help string for that option).

This can be conditionally enabled in the future when MCP
supports e.g. Ceph as a backend for shared instance storage
on computes.

This patch picks default value from nova service unless it is
configured via compute:libvirt:live_migration_tunnelled option.
Starting from Newton is disabled by default.
