This change fix ansible deploy ovs-dpdk failed and
neutron_openvswitch_agent container can't start..
dpdk_tunnel is a role variable, but kolla_address gets vaule
from hostvars. so we need remove this variable and it's friends
to group/all.yaml
neutron_openvswitch_agent connects to ovs-db with 127.0.0.1,
but ovs-db listen on management interface.
