[cifmw_backup_restore] Add Octavia OVN sync after Neutron sync

Sync Octavia load balancer entries to OVN NB database when Octavia
with OVN provider is deployed. Checks spec.octavia.enabled on the
OpenStackControlPlane CR, skips if Octavia is not enabled.

Placed right after the Neutron sync and before EDPM deployment so
OVN NB DB is fully populated when data plane nodes reconnect.
