Fix Kayobe overcloud introspection data save

Kayobe overcloud introspection data save fails because the dynamic
inventory script siliently breaks causing Ansible to parse it as a
static inventory file. The failure occurs due to OS_TOKEN being set.
This change works around setting OS_TOKEN before running the dynamic
inventory script by setting OS_CLOUD before querying inspector.

Confirmed on Stein and Train, and verified in both environments.
