local_ip is empty in multinode

[Yuli]

When running stack.sh in multi-node I am getting the following error on the compute node:

CRITICAL neutron [-] ConfigFileValueError: Value for option local_ip is not valid: IP address cannot be an empty string

A workaround is to add the following line to configuration:

TUNNEL_ENDPOINT_IP=$HOST_IP

I think changing all config files is not a good idea.

I will fix it by setting this value in devstack plugin.sh
