devstack should put admin_tenant_id in tempest.conf file while setup

Some of the test cases in tempest related to quota use
admin_tenant_name, ideally it should use admin_tenant_id.
As tempest.conf file does not contains admin_tenant_id
it should also be updated. tempest.conf file is generated
by devstack while setup of openstack, changes should be made
in devstack so as to put admin_tenant_id in tempest conf file.

Use identity_uri instead of auth fragments

auth_token middleware now accepts a standard URL string as the parameter
identity_uri instead of specifying protocol etc individually. Change the
services over to use this.

Also changes over some other places in which the auth fragments are used
individually to the new variables and fixes up some misconfigurations of
auth_token.

identity_uri option was release in keystoneclient 0.8.0
