Deploy glance-cache on far-edge nodes via Split Controlplane

Registered by John Fulton

The initial implementation of the split control plane will run the glance-api service only on the controller node with the swift backend and then remote compute nodes will GET the glance images for their instances.

This blueprint tracks the changes required for TripleO to deploy glance-cache [0] on the remote compute node.

Changes made to implement this feature should have symmetrical changes made in the split contorl plane CI job [1] to prove that the change worked.
