If DaemonSet contrail-agent need toleration ?

[heisenbergye]

Learning from contrail-standalone-kubernetes architecture, there is no need to deploy contrail-agent on the master node，so I delete the spec.template.spec.tolerations in DaemonSet contrail-agent. Because the vhost0 has a network failure after contrail-agent initialized on the master node，although there is a default route via vhost0 in host's route-table.
