Restore ServiceAccount to openvswitch pod

This change includes back the the helm-toolkit snippet:
kubernetes_pod_rbac_serviceaccount to the openvswitch Daemonset
definition, since it is responsible for creating the POD's
ServiceAccount which contains imagePullSecrets that enable the POD to
retrieve images from private registries.

Originally openvswitch chart had two daemonset definitions: for the
db and for the server, but recently both were merged into a single
daemonset [1] and the template inclusion was dropped during this merge
