Title:
  local_ip should be validated when ovs-agent starts

Status in OpenStack Neutron (virtual network service):
  In Progress
Status in Oslo - a Library of Common OpenStack Code:
  Fix Released

Bug description:
  https://github.com/openstack/neutron/blob/2702baed390d094b0eac07d0ae167ed236868d00/neutron/plugins/openvswitch/agent/ovs_neutron_agent.py#L1327

  The ovs agent will currently accepts anything for local_ip, and sends
  it to the plugin with the sync_tunnels rpc, and then all other agents
  will try to make tunnel ports using it as the remote_ip. Then the only
  way to get rid of it is to manually delete the row in the DB.

  If tunneling is enabled, netaddr.IPAddress() could be used to validate
  that local_ip is a proper IP address. Only IPv4 tunnels are currently
  supported for GRE - not sure about VxLAN. Maybe a check that local_ip
  actually exists on the host too.
