With recent version of libvirt, nova-compute don't come up
correct when tls-everywhere (use_tls_for_live_migration)
is set. The enable_live_migration_tunnelled condition
did not consider tls-livemigration and got disabled.
Nova-compute fails to start with:
2021-05-12 12:49:09.278 7 ERROR oslo_service.service nova.exception.Invalid: Setting both 'live_migration_tunnelled' and 'live_migration_with_native_tls' at the same time is invalid. If you have the relevant libvirt and QEMU versions, and TLS configured in your environment, pick 'live_migration_with_native_tls'._
This change enhance the enable_live_migration_tunnelled
condition to not configure tunnelled mode when
use_tls_for_live_migration is true.
