Update backend samples using custom images

Te way custom images are specified has changed, and now it no longer
uses the `containerImage` file in the cinder sections but instead needs
to be specified in the `OpenStackVersion`.

This patch updates the examples to match the latest code.

 Some backends, like 3PAR and Pure, require a custom container because they have
 external dependencies. So there is a need to build a specific container. In
-RHOSP, vendors will provide certified containers through Red Hat's container
+RHOSO, vendors will provide certified containers through Red Hat's container
 image registry. For illustration and development purposes this repository
 provides samples of what a `Dockerfile` would look like for each of the
 vendor's. This `Dockerfile` will be present in the vendor's directory (e.g.
 `hpe/Dockerfile` and `pure/Dockerfile`), so we would need to build a container,
 make it available in a registry, and then provide it to the cinder operator via
-the `containerImage` as seen in the samples.
