This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository.
At present, when provisioning in a cluster, it blocks a long time waiting for OpenStack to do what it needs to do. This has a knock on effect for UX in that said delay is visible in the UI and CLI tools. This lays down the groundwork to make this asychronous so we don't hold up uer interaction, but we do cluster provisioning. This is a template also for phyiscal network provisioning that takes even longer, and causes request timeouts that need to be avoided.
