Public bug reported:

OVS agent tunnel interfaces are named via:
'%s-%s' % (tunnel_type, destination_ip)

This means that the tunnel interface name is not unique if
two OVS agents on the same machine try to form a tunnel with a
third agent. This happens during full stack tests that start
multiple copies of the OVS agent on the test machine.

Making sure that the tunnel interface names are globally
unique on a host adds support to full stack tests that need 3+
OVS agents.
