Improve quantum l3 and tempest config.

 * Previously, configuration for the q-l3 agent was creating a
   tenant-owned router.  This change maintains that behaviour if
   namespaces are enabled, but creates a public (not tenant-owned)
   router if namespaces are disabled.  Since the L3 agent can only
   manage a single router if namespaces are disabled, the change
   ensures that the single router can be shared by multiple tenants.
 * Add tempest configuration for the public router.
