    Add tenant-id to subresources

    When a tenant access a subresource, neutron will check that this
    tenant is allowed to view this subresource, according to the policy.json.
    The plugin must return the tenant_id parameter when a "show/list/delete"
    action is performed, so that the policy framework can check authz.

    This patch also set the network_id as a mandatory parameter
    in the network_association table.
