Tech Debt: Reverse temporary gate fix

[Adrian Otto]

On 2015-07-10 changes in Devstack broke the Magnum gate. We are working around this breakage with this patch:

https://review.openstack.org/200835

This happened because the changes are not compatible with the Keystone v2 API, which Magnum uses.

We have asked Devstack to re-implement their changes in a way that will not break us in the future. While we wait for that, we will use our workaround. Once Devstack has been changed in accordance with suggestions from here:

http://lists.openstack.org/pipermail/openstack-dev/2015-July/069398.html

Once Devstack is no longer setting the following environment variables (which are incompatible with Keystone v2 API):

OS_PROJECT_DOMAIN_ID
OS_USER_DOMAIN_ID

Then we can remove the code added by review 200835, as it will no longer be needed. This ticket should be acted upon once this condition is met.

Change abandoned by yatin (<email address hidden>) on branch: master
Review: https://review.openstack.org/338472
Reason: Devstack still sets this variable for v2 keystone API, so needs abandon
