cookbook-openstack-network can not enable vxlan

[Wei Hu]

The cookbook-openstack-network can not enable vxlan because of missing the tunnel_types in ovs_neutron_plugin.ini.erb template file.

neutron ovs_neutron_plugin.ini tunnel_types parameter:
https://github.com/openstack/neutron/blob/master/etc/neutron/plugins/openvswitch/ovs_neutron_plugin.ini#L190

cookbook-openstack-network ovs_neutron_plugin.ini missing this parameter:
https://github.com/stackforge/cookbook-openstack-network/blob/master/templates/default/plugins/openvswitch/ovs_neutron_plugin.ini.erb

Don't set this parameter, will cause nova boot failure. And can get the following warning message in neutron server.log:
2014-08-13 16:43:54.335 7418 WARNING neutron.plugins.ml2.managers [req-1fc3fc8b-855b-4809-a2a9-e750ed1f81a0 None] Failed to bind port 43ae6095-096c-44a5-b0fe-5b57207e39f2 on host comptest.ibm.com

In compute node can see the boot failure message:

    Add tunnel_types in ovs_neutron_plugin.ini.erb

    Nowadays, there is no tunnel_types item in ovs_
    neutron_plugin.ini.erb template. And user can not
    assign value to this item by environment. Therefore,
    the vxlan enablement will failure because of the item
    default value is '[]' which will disable tunneling
    support in the agent.

    Fixes bug #1355663
