OS_AUTH_URL in overcloudrc points to keystone API v2.0

[Alfredo Moralejo]

Periodic OVB jobs in master are failing in "overcloud-deploy : Run post-deploy script" task wit error [1]:

2017-10-25 17:32:52 | (http://192.168.24.8:5000/v2.0/tokens): The resource could not be found. (HTTP 404) (Request-ID: req-bd730f45-0618-4976-b294-1bbc8353b9d0)

The problem seems to be that overcloudrc file is still using keystone api v2.0 for OS_AUTH_URL [2]while v2.0 has been removed from keystone.

    Provide a quick workaround for 1727454

    Tripleo-common provides an overcloudrc and an overcloudrc.v3 by default.
    Problem is that Keystone v2 API was removed in Queens, so we can't rely
    on overcloudrc file anymore.

    Until we fix that in tripleo-common, let's source the overcloudrc.v3
    after Pike, so we can promote to Queens.

    This is technical debt that will be cleaned asap.

tripleo-common gets the KeystoneURL from Heat with https://github.com/openstack/tripleo-common/blob/master/tripleo_common/utils/overcloudrc.py#L48.

We have use a nasty hack for some time to make the /v3 version.

https://github.com/openstack/tripleo-common/blob/master/tripleo_common/utils/overcloudrc.py#L115

So I think this needs to be fixed in t-h-t? I am trying to track down where this value comes from.

    Make KeystoneURL versionless

    Now that Keystone v2 has been removed, we can update this to a versionless
    path. This output is used by tripleo-common to populate the overcloudrc file.
