Problem:

For users using K8S versions 1.8 and lower that don't have the fix contained in kubernetes/kubernetes#53115 it may be necessary to set bs-version for the OpenStack cloud provider when installing on OpenStack clusters that expose their Cinder endpoint using paths rather than ports to avoid auto-detection errors such as:

Failed to attach volume "jenkins2-volume" on node "app-node-1.openshift.staging.xxxx.co" with: BS API version autodetection failed.

This includes for users trying out K8S on a devstack environment, and potentially other deployment tools. In this situation it is possible to resolve using:

[BlockStorage]
bs-version=v2

Valid values for bs-version are:

• v1
• v2
• v3
• auto

With auto being the default.

Proposed Solution:

Highlight the bs-version parameter as optional (so not minimal configuration) but required in some circumstances.
