On OSP deployments that use networker nodes, such as composable or
upgrade, some Octavia services run on the networker nodes instead
of the controller nodes.
So far, the method _start_octavia_main_services tried to start all
octavia services for each node, because of a typo.
This patch fixes the issue by making sure that for each node, only the
stopped Octavia services will be rerun.
