Add a job for testing zun standalone deployment

After integrating with placement, there are two deployment mode:
* Hybrid mode: a compute host resource provider is managed by both
  nova-compute and zun-compute.
* Standalone mode: a compute host resource provider is managed by
  zun-compute solely.

This commit adds a job for testing standalone mode. The hybrid mode
is covered by existing jobs.
