notes:
- One environment variable needs to be set: RAX_CREDS_FILE.
- RAX_CREDS_FILE points to a credentials file appropriate for pyrax.
- RAX_CREDS_FILE is an optional environment variable that points to a pyrax-compatible credentials file.
- If RAX_CREDS_FILE is not supplied, rax.py will look for a credentials file at ~/.rackspace_cloud_credentials.
- See https://github.com/rackspace/pyrax/blob/master/docs/getting_started.md#authenticating
- RAX_REGION is an optional environment variable to narrow inventory search scope
- RAX_REGION, if used, needs a value like ORD, DFW, SYD (a Rackspace datacenter) and optionally accepts a comma-separated list
