update share's container image when new version is released

It would be great to automatically manage the container image updates. On OpenShift, it could use imagestreams and triggers. But that's hardly a general option.

We'll look into it. Without reading any I'm not sure what those are at the moment, so we'll need to do some research if it's appropriate for our operator.
