Keystone endpoints default to v2 in Newton

[Amy Marrich]

Even with answers.txt configured for Keystone v3:

# Identity service API version string. ['v2.0', 'v3']
CONFIG_KEYSTONE_API_VERSION=v3

Endpoints are created as v2:

openstack endpoint list --service keystone
+----------------------------------+-----------+--------------+--------------+---------+-----------+----------------------------------+
| ID | Region | Service Name | Service Type | Enabled | Interface | URL |
+----------------------------------+-----------+--------------+--------------+---------+-----------+----------------------------------+
| 302ce541b95848ee9f9887c74a0f2f13 | RegionOne | keystone | identity | True | admin | http://XX.XX.XX.XX:35357/v2.0 |
| 7550772dab594953a05275f8a810eb14 | RegionOne | keystone | identity | True | public | http://XX.XX.XX.XX:5000/v2.0 |
| 947ca345c4e84206bc0f3894ebe86283 | RegionOne | keystone | identity | True | internal | http://XX.XX.XX.XX:5000/v2.0 |
+----------------------------------+-----------+--------------+--------------+---------+-----------+----------------------------------+

keystonerc files and local_settings files are set for Keystone v3.

    export OS_USERNAME=admin
    export OS_PASSWORD=openstack
    export OS_AUTH_URL=http://XX.XX.XX.XX:5000/v3

export OS_PROJECT_NAME=admin

export OS_PROJECT_DOMAIN_NAME=Default
export OS_IDENTITY_API_VERSION=3

local_settings

Fix proposed to branch: stable/newton

Change abandoned by Javier Peña (<email address hidden>) on branch: master
Review: https://review.openstack.org/471062
Reason: I'm abandoning the review on master and just keeping the one for stable/newton [1]. Since we need to have a keystone v3 endpoint for the Nova Placement API to work, this doesn't make much sense on master. I'll check the options to remove keystone v2 support completely in Pike/Queens.

    Set Keystone endpoint version according to answer file

    Previously, we were hardcoding the keystone endpoint version in the
    catalog (v2.0). Let's use the version provided in the answer file instead.
