Stop nova services before doing a db sync; start them after the sync

Sometimes, running openstack_nova.sh results in several nova-conductor
services being created.
To avoid that, one solution is to stop the nova services before doing a
db sync, and to start them after the sync.

One solution is to directly ask the user for the IP.
