Title:
  auth_url contains wrong configuration for  metadata_agent.ini and
  other neutron config

Status in neutron:
  Invalid
Status in openstack-ansible:
  Fix Released
Status in openstack-ansible liberty series:
  Invalid
Status in openstack-ansible trunk series:
  Fix Released

Bug description:
  The current configuration

  auth_url = {{ keystone_service_adminuri }}

  will lead to a incomplete URL like  http://1.2.3.4:35357 and will
  cause the neutron-metadata-agent to make bad token requests like :

  POST /tokens HTTP/1.1
  Host: 1.2.3.4:35357
  Content-Length: 91
  Accept-Encoding: gzip, deflate
  Accept: application/json
  User-Agent: python-neutronclient

  and the response is

  HTTP/1.1 404 Not Found
  Date: Tue, 01 Mar 2016 22:14:58 GMT
  Server: Apache
  Vary: X-Auth-Token
  Content-Length: 93
  Content-Type: application/json

  and the agent will stop responding with

  I seems we need to change the template to use actually
  keystone_service_adminurl like

  auth_url = {{ keystone_service_adminurl }}
