Ability to run the openstack tests against DevStack

**What this PR does / why we need it**:

Some of the environment variables have changed as devstack defaults
have changed. So look for the older env variables first and try the
newer ones later.

At a minimum you need the following for v3 authentication which is
the default with latest devstack. If you miss the Tenant information
then the token issued will be a unscoped token (and will not have any
service catalog information).

OS_AUTH_URL=http://192.168.0.42/identity
OS_REGION_NAME=RegionOne
OS_USERNAME=demo
OS_PASSWORD=supersecret
OS_TENANT_NAME=demo
OS_USER_DOMAIN_ID=default


**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes #

**Special notes for your reviewer**:

**Release note**:
