Fixes an issue when using ip addresses instead of hostnames in Ansible
inventory. OpenvSwitch role sets system-id based on inventory_hostname,
which in case of ip addresses in is first ip octet.
Such a deployment would result in multiple OVN chassis with duplicate name
e.g. "10" connecting to OVN Southbound database - which spawns high numbers
of create/delete events in Encap database table - leading to near 100% CPU
usage of OVN/OVS/Neutron processes.
