[Openstack-operators] l3 ha using vrrp

Only the controller (running neutron-server) contains the ML2 plug-in
([ml2*] options in ml2_conf.ini) and schedules routers (L3 options
neutron.conf). Use of ml2_conf.ini on other nodes is a bit misleading.
However, prior to Liberty, configuration for L2 agents that reside on
network/compute nodes commonly went into ml2_conf.ini for convenience.
Liberty uses openvswitch_agent.ini or linuxbridge_agent.ini for L2 agent
configuration, therefore eliminating the ml2_conf.ini file from
network/compute nodes. Updates to the networking guide for Liberty will
reflect this change.
