Gate Tests are failing because of removal of KEYSTONE_CATALOG_BACKEND by Devstack

[yatin]

Recently devstack removed KEYSTONE_CATALOG_BACKEND from it's repository: https://review.openstack.org/#/c/391380/

Magnum specific description, but affect's other project.
--------------------------------------------------------
In magnum this variable is used so test's started failing because endpoint didn't get created.

2016-11-23 03:32:50.438 | ++ /opt/stack/new/magnum/devstack/lib/magnum:create_magnum_accounts:111 : [[ '' = \s\q\l ]]

The above condition should have passed for creation of magnum endpoint. But since the variable is removed the condition failed.
